Wireless Set 19

[Chris Suslowicz]

The spacer was made in a variety of materials, presumably down to what was available at the time/place of manufacture.

British ones are/were made of rubber (I've seen white, brown and black examples).

Canadian ones were made of plywood, with cork gaskets glued to top and bottom in order to keep water out.

Post-WW2 (possibly later WW2) British ones were made from steel stampings, as two shallow dishes welded together along the seam, and rubber gaskets were used (which continued into the Larkspur era with a variety of bases).

Best regards,
Chris.
