Wireless Set No. 52 Canadian - Project

[David Dunlop]

I have had a chance to compare this Aerial Base C2 to the diagrams of it in the 52-Set Instruction Manual. It looks like only two pieces are missing: a small wire D-ring at the very bottom of the assembly, used to retain the wing nut, and, the large 9-inch square, 1/4-inch thick, brown, phenolic plate which fits between the two ceramic insulators.

Drawings of the plate with specifications are provided in the Instruction Manual for everything except the central hole in the plate.

In order to provide effective RF Insulation in transmit mode, this central hole at the very least has to be large enough to safely clear the central conducting core of the aerial base. At its largest, it might be sized to allow the large collars of the two ceramic insulators to lock into the plate on either side to hold the aerial base in position.

Is there a surviving phenolic plate assembly out there somebody can reference the central hole size from, for me?
