I have found www.collinsradio.org (the Collins Collectors Association)
on the net.

Are there other users' groups, with websites and/or mailing lists, for
other older gear e.g. Swan, National, Hallicrafters, Heath?

For those interested in equipment made by KW Electronics in the UK in
the 1960s and 70s try:-

We have several members from the USA.
