Old-Time Radio Researchers
https://www.otrr.org/A search didn't turn it up here in a topic.
There is an 'OTR Magazines' section, inside which you can select the publication, such as Allied Radio Catalog, and other radio related publications.
The site is mainly about generalized Old Time Radio and has old radio shows and old comic books etc., which is an interesting thing in itself, but there are the radio catalogs and magazines if you look for them.
