eames help  

I'm guessing
Vitra.... 60s or later.

Ding! Ding! Ding! Woodywood you're correct!
60's or later. Vitra
I've had numerous shells and have never seen the shockmount locations to be so pronounced.
Nice contract color.

thanks
Thanks for the info, I have got the chance to buy a few what colour would you say they are (look grayish)

Hard to tell
From the photos, but I think it looks like Greige, which is a nice but common color.

vitra
hi you say vitra i have found the rubber shocks have the Herman miller logo on what does this mean the chairs are or the rubber? is sorry to ask but don't know to much on eames thanks again

Curious....
I would guess that could mean that the shock mounts were made by Herman Miller and sent to Vitra for assembly. However, I'm not aware of any US shock mounts being marked with Herman Miller. I have never seen a vintage Vitra chair in person so this is just my speculation.

hi i will post a pic

here are the pics

HM logo on shock mount?
Backing up woody's comment, I've owned hundreds of these chairs, and have never seen the HM logo on the shock mounts. There are often letters and numbers on them, but I assume those to be lot or mold cavity markings for quality control.
Maybe it's a Vitra-specific thing. Seeing the new pictures, the legs also appear to be something other than Herman Miller / U.S. production (too shiny).

thanks
Thanks for that as I said I don't know to much about eames, these chair have come from Belgium

At least they are narrow mounts.
And should be easy to change over to more desirable bases.

to many
I've done that to some but I have 40

V is not for Vitra
Back in the early 1950's most of the stacking chairs were sold for institutional or commercial use and have no need for interchangeable bases. Your fiberglass side shell is an earlier shell model with a later shock mount location and a later stacking base option. The earlier stacking or linking bases used to have a different shock mount locations as shown in your shell compared to the other shells made for the other bases. Someone at HM probably realized later that they could reduce the work involved if all the shells will have the same shock mount location making the bases really interchangeable.

Maybe not
But I still think it's Vitra production.
