Looking for second series Eames ESU legs  

Hello,
I have purchased three pieces of second series eames storage units, which have had the legs removed, and the previous owner added casters on the bottom (ouch). These are the chrome round legs with the kind of triangular shaped bracket (see attached pic). Do any of you experts out there know if anyone makes these, or has seen any for sale? I hear a lot of the original parts that were used for these were sourced from military surplus etc...
Or by some miracle does anyone have any you would like to sell? I am planning to try and get some fabricated, but figured I would check on this great forum fist to see if anyone has any leads... Any help would be greatly appreciated!
Thanks, John
