Paul McCobb Credenza/ ???  

Oh and..
Oh and, if it is McCobb, what did he call this piece? Credenza? Sideboard? Commode?

Great find
That there is a Paul McCobb designed #1510 20-Drawer Mr. and Mrs. Chest for the Planner Group which was first shown in June of 1952.
The very earliest versions of this chest would not be "signed" as they predate the establishment of the Paul McCobb branding mark for the Planner Group.
As far as the wrought iron bases go, the chests were (and are) very heavy. It's not entirely unusual to find them just placed down on the bases and not screwed in as it was not particularly easy to shift them once they were set in place.

Thank you so much!
That is great to hear. Thank you for the ID!
Can anything regarding the age be gleaned from the type of drawer pulls I have, half being knob like, and half being t-shaped? And the fact that my credenza has 5 legs, one on each corner and one centered, not 4 or 6? Were the 6 leg bases, and the all-t-shaped-pulls alternate options that ran concurrently?
Oh and while I'm picking your brain: I see this called birch, I see this called maple.. I even see it called "blonde mahogany" which seems impossible.. What is it actually made of?
Thanks for your help!

Fees please
Since you have used my text for your eBay listing (and a photo you lifted from 1stdibs, don't you own a camera?) I will expect to receive 5% of your sale price or $200 whatever is the higher number.
Not that you will ever sell it for the 6k+ asking price that you have on it and total feedback as a seller of ZERO.

As a matter of fact
As a matter of fact I'm shooting my own pictures now.. Normally on ebay, your listing doesn't begin to show in the search results for 24 hours. So we wanted to get those first 24 hours started as soon as possible.
If you're actually upset about the date information on there, I'll go ahead and remove it. But to act like I didn't know what I had until you saved me from my ignorance is a bit much. All I needed to know was if what I had was authentic or not, sans a signature. Didn't want to rip anybody off.
In any case, thanks again.

Ebay
As an experienced ebay seller, I can tell you that your listing is available as soon as you post it. Whoever told you about a 24 hour lag is wrong. For that reason and others, (perceived deception) I can not see posting a lifted photo doing anything for you other than to suggest to the viewer that you are up to something. This is the impression I got from your listing having "borrowed" text, photo, and a price roughly three times more than than your item is worth.

Part 2
I think Straylight was interested in painting me as some drive-by 'Picker' type, because they are certainly common here and it fed his sense of indignation. And I can understand it and I'm not offended by it, but it simply isn't the case. I use this site daily to learn about mid century design. I use lots of sites for that same purpose. As a matter of fact, I learned from a thread previous to this one that the Aalto stool I have in my shop is likely authentic, when I had assumed it was a knock-off. Am I allowed to use that information for my own benefit, because in that case it was someone else who asked the original question? Or do I have to buy a book to use the information?
Or what about the next person who google's McCobb dressers and finds this thread? Is he allowed to use the information that his is authentic even without the stamp?
If we are telling the truth, virtually everyone HERE is buying and selling items, if not for their living, at least largely for profit. And virtually everyone here can learn something new every time they click through the forums. I would freely contribute my information, if there weren't so many people around here better at it than I. As another example, in a thread about Cherner chairs and Plycraft, I was going to post a photo of my Cherner chair from my shop as another variance on the design, only to find that Woodywood had already posted MY photo. He didn't source the information, or the picture back to my shop. Not that I cared or care, I didn't intend to link it back to my shop anyway. Just another example of people using this forum, and the internet as a whole, to further their knowledge.
And as a side note, regarding the price, I find that kind of funny too. I've gotten pushback on my Etsy shop from unknown dealers because I had an item or item priced too low, I was going to ruin the market. You just can't win with that. I know I'm not going to get 6k for it, but if everyone priced it at $2k because that's what the last guy got, you'd never find true value for anything.
I digress. Sorry to waste everyones time, and sorry again to Straylight.

That is good to know - Part 1
That is good to know, regarding the 24 hour window. I actually am new to ebay, as far as selling. I run an Etsy shop, and sell there mostly, because of lower listing fees and the "Shop" feel of it. I like that it feels like a virtual brick-and-mortar shop, rather than just an auction house. But I've found that for higher end items, there just isn't as much of a market there.
When I sold my first item on ebay six weeks ago, it took 3 days for my listing to show up in searches. When I listed my second item three days ago, it took one full day. I called ebay the first time and they explained that there is often a 24 hour lag where the item is present for direct linking, but doesn't return in search results.
I do admit the use of the photo from 1st Dibs was a faux pas, but like I've said, I wanted to get my listing in to the results ASAP, and intended that photo simply to be a placeholder. I have no internet connection at my warehouse, so I posted the item, shot the pictures, came home and posted the new photos. In the interim, my listing had 9 views, until I was "called out" here, and 25 more people went looking for me.
This stuff with using Straylight's 'text' is a bit of a reach. I bought this credenza because I knew what it was. It's got 10 - 15 stamped in the back, I can count the 20 drawers. The listing I "lifted" my photo from on 1st Dibs was for a Mr. and Mrs. Dresser. You search "McCobb 20 drawers" on google, and you can find sold items all over the place listing the name of the piece and the year it was released.
But I was a concerned regarding the absence of a stamp, and the detached base, so I came here for help.
Straylight gave me an extra bit of info, in telling me that the absence of a stamp likely means it's an earlier piece. I can completely understand him feeling like I was taking advantage of his good nature by including this info in my listing. Mea culpa. I took it out.

Are you Jeremiah
using an assumed name? You have made three errors that I can't just let you get away with. First, you used a picture on ebay that was not your actual item. OK, you apologized on this website, but that doesn't help the poor saps on ebay who looked at your maple chest that wasn't even your maple chest. Huge no-no.
Secondly, you are mistaken if you think that everyone on DA is here to make a profit. The majority of people here follow this website to learn and to critique and to dispense advice. Don't paint everyone with your own capitalistic brush.
Finally, that was a ridiculous statement regarding the 6,000 USD price. Doesn't it tell you something that EVERY OTHER ONE of those chests sold for around 2,000 USD? You are just feeling out the market or what? Good luck with that strategy.
I feel like I need to go take a shower.

I understand what you're saying
I understand what you're saying Riki, but I guess we just disagree.

eBay
strictly forbid the use of other seller's pictures, from whatever source.
Likewise description texts.

Tacky...
I'll add to the chorus of not everyone here is too make money or sell their finds. Im not a dealer. I sell on occasion only because Ive managed to find a better piece and will sell the old piece I no longer have room for or when I find something at an estate sale I can't pass up, but then have to admit I don't have the room or decor to go with. It is still embarrassing to admit how much I have in storage, because I can't bring myself to sell it (& in hopes of using it in the much larger home I will own one day)
95% of what I post on here are things I've bought for my home and want to know more about. I do appreciate the dealers on here sharing their knowledge with us. I know the pros on here enjoy helping people who are in love with the finds they gotten for their home, but have to be a little sour with the crass way others try to use their hard earned knowledge to milk a little more money out of the piece on eBay.
It is tacky to run on here asking about a "find" and within an hour of getting a helpful answer - using that exact answer to create a description for the piece for a post at a ridiculous price on eBay and even using a stock photo of it. The speed at which you did list it is amusing, like some one is just going to snap it up at that price and there was no time to waste.

This thread is a good reason...
This thread is a good reason not to buy overpriced pieces from opportunist
"dealers." McCobb was dept. store goods for working people - and very cool because of that - but also not rare and not George Nelson or Mies or anyone else. I love McCobb's designs and have several pieces - but I would never pay that much, and this thread is a big reason why.

Not all McCobb sold in dept stores
A quick note here to address a few points.
As the 50's progressed the showroom programs of most of the major manufacturers gave way to selling in department stores as the more venues available drove greater volume sales.
The market was rapidly realizing that volume beats exclusivity, so much so that most of the showroom producers had, by the late 50's, almost entirely abandoned their showroom operations for the much more lucrative contract market. The very best example of this is Herman Miller's handling of George Nelson and Charles Eames work in the late 50's early 60's where their byword became mass produced for contract.
McCobb's Planner Group was certainly a department store line, as was his Perimeter Group and Linear Group but his Directional collections were not. Directional was strictly a showroom operation. I think Protorio is correct in that there really should be more of a distinction made between McCobb's work for the Showroom and his department store collections. But that is just one man's opinion.
As far as rarity of Planner Group pieces goes, there are some exceptionally rare designs for the Planner Group and much that is common
