Wireless Set No. 52 Canadian - Project

Hi Chris.

Good question on the original pin diameter size. That little detail is missing from the Master Parts Listings. They do, however, identify that the slot in the AE Terminals into which the pins fit, are 1/8-inch deep and I found a 1/8-inch drill bit shank slides in and out quite easily.

The other factor that I ran across is that the 1/8-inch pin size seems to have been a standard for many decades for the Motorola Connectors used with automobile radio aerial leads. At one time I think the sockets used to have spring loaded innards that gripped the aerial connector sleeve to hold it in place, but todays versions appear to have switched that up. The spring grips are now on the connector sleeve, or they use a bayonet type lock.

Years back, a smaller version of these pin connectors were common for speaker and headphone connections to wireless equipment, so that might be another possibility for you Chris.
