Does anyone have a good late 50's early 60's parts catalog?

[Lee Blaske]

Somebody's got to have some old parts catalogs in their boat anchor
library. I'd be extremely grateful if someone could look up the specs
for a part that's no longer available used in a modification circuit
that I'm considering.

The part is a Potter & Brumfield LM11 relay.

I know it's a DPDT relay with a 10,000 ohm coil, but I'd like to know:

What is the nominal coil voltage?
AC or DC?
What are the contacts rated for?
What are the dimensions?

Thanks in advance.

73,

(Is there a remote chance that someone has one of these gathering dust?)
