Hi, I just recently got a Faraday Unipact #3234, Type 511 120AC vibrating bell from eBay.
It works well, just had to remove an old mud dauber wasp home (already vacant)
I had to add the securing screw to the base.
It’s an older Unipact bell because there are differences between the original and it.
I’ve been looking for older catalogs on it, but Glenn J. has provided me catalog pages on the earlier versions.

I think you should tell him to scan those catalogs and upload them to the Building Technology Heritage Library on the Internet Archive, which is right here: Internet Archive: Digital Library of Free & Borrowable Books, Movies, Music & Wayback Machine
There’s only one catalog on FA hardware and that is a 1938 Wheelock catalog.
anyway, I believe this bell is from the mid- late 60s, when they moved from Adrian (both of those towns are in the same county of SE Michigan) to a larger facility in Tecumseh
