Rosewood tipped legs  

Looks like Poul Hundevad to me!

Thanks for the reply! I do see similarities in its simplicity. But never found anything Hundevad with these rosewood tipped legs.

In the last photo it appears the legs are held on with metal brackets? Or are my eyes deceiving me?

Yes, the legs are attached with a metal bracket.

Well, where did you purchase the cabinet? Could they have been added? Can you snap a photo of the bracket?

I guess the legs could have been added. Here is a photo of the bracket.
The cabinet came from Washington D.C.

Sorry, I meant did they come from the owner or a dealer? Is that a circle marking for another set of legs or cobwebs?
I found a similar one here with a square base. If you removed the base and added legs, you'd have your cabinet. http://www.uniquesandantiques.com/061113catalog/4cat.html
Now, Hundevad for example made cabinets with and without legs, I just trying to help! 🙂

It came from a dealer. Here's something a little odd I found when wiping away, yes, those were cobwebs. There are two brackets underneath that seem out of place.

Yes it has definitely been altered one way or another. I can't figure out what those brackets were used for. But hopefully someone else can.

Even though bastardized, it is still a very well crafted piece. Thanks for all your time looking at these photos. If anyone else has any ideas, I'm curious what it might have been in its first life.
Thanks again!

My last question for you; the back piece of teak looks almost new, do the sides look the same as the back or more like the doors?

I think the photos are a bit misleading. Nothing new about the wood and it's clearly all the same ear. The photo of the back was taken in shadow and the photo of the front was taken with glare from the window and lights ect. In person the front looks as good as the back -- it's just bad photography and bad lighting.

Could it have been part of a wall unit and those brackets on the bottom rested on a support rod between standards? I don't know much about how Danish wall units are constructed, that's just the first thing that popped into my head. But they also look like they're pine, in which case I would guess they were added later.

The leg brackets have been attached with flat head screws, which makes them seem a very old addition, if they actually are an addition.
Why are there holes, and so many of them, in the bottom of the cabinet?
If it were for a wall unit, it would have to pertain to a free standing room divider type wall unit. Otherwise there would not be a finished back. Also, there is not provision made for attaching the top rear of the case to anything, and this is where the weight would pull most. So the only way it could support weight is if the frame has some sort of base for the bottom of the cabinet to rest upon. The cabinet could not be used higher up on the frame, which seems contrary to the modular, arrange it yourself mentality. And I've never seen such a thing in a Danish wall unit or room divider.
All of this makes me think it probably is not part of a wall unit.
