Warbird Information Exchange

Hello,
Doing some research on the Schick-Johnson compnay and the seats they manufactured. The most famous were the ones fitted to the P-51 and T-6 (same seat!). I have done google searches ect. and cannot find one bit of information of where this company was located , and what ever happened to them. merged, bankrupt? Also (I know this is a LONG SHOT) is there any specific manuals or blueprints out there for this type of seat? I have the IPC breakdowns from both the T-6 and P-51 manuals for the seats, but I am looking for more detailed dimensional information. Anything that my fellow WIXer's can provide would be very helpful and very much appreciated!

I have an extra one in Chino you can measure if you want.

The Schick-Johnson Company was located at 1737-45 North Paulina St. in Chicago, IL. No further information after WW2.
