lot vintage bakelite electrical parts lamp sockets, plugs, switches for industrial lighting etc

Large lot of vintage bakelite light sockets, plugs etc., most 1930s - 1950s I believe. These are pretty clean for the most part, but many have been used and all are untested. The whole lot is shown all together in the first photo.

There's some really interesting pieces here - the two part fittings with the metal cages, an unusual Bryant switch, NOMA and Handy plugs. And lots of regular bakelite plugs, a few sockets and more.

24 pieces in all.
