I can't quite tell from pictures but it appears that Moog used the metal can 796 in 921b modules. Hope this helps.

Reversible Atteunator
Hello. This is my first post and I just wanted to share some info I found. I'm in the progress of building a clone Modular based on the 15 ( there are a few differences like a 901a/bb combo instead of a 921a/bb and a cp3 mixer). When building the CP15 console panel, the schematic was very blurry and...
