[Milsurplus] Wanted - 1" dia female AC mains connector

[Nick England]

Howdy men - I'm looking for an AC mains connector for a Navy
stabilized master oscillator (Collins 708A-1 with variants O-91/FRT-5,
O-212/FRT, and O-243/FRT-24 - basically a 31-tube VFO).

125v 15A female 2 wire, polarized straight blade -(NEMA 1-15R)
 2-piece round bakelite housing
1" diameter - this is the key spec since it needs to fit into a
recessed receptacle on rear of the oscillator - visible here -

Original connector is General Electric # 2716, but not listed anywhere
I can find - everything else I see is too big.

In case you have an extra or two in your junque box... or suggestions
for an equivalent - I've looked at a number of 2-wire extension cords
but so far nothing that will fit or can be shaved to fit.

Thanks,
