Anyone have a 1950's Centralab catalog?

[CaryLee]

Or know where I can find one on the net? I found a catalog from the 1940's but that's too early.

I'm trying to find the part number for the switch cover for the on/off, volume, and hold control on my 1950 DuMont RA-112.

The SAMS Photofact doesn't break down the individual components, but lists the a Centralab part number: SBB-560-S, which I believe is the whole assembly.

The switch cover MIGHT be a KR-1. Does that sound right? The IRC equivalent is a 76-1, but I don't know if an IRC cover will fit a Centralab control.

Thanks.
