[Boatanchors] WTD:CANNON PLUG

[Dee C. Almquist]

Fellow Anchorites
Am in need of a cannon plug that measures little less than 3/4" is dia (threads). inner "sleeve" is 4 prong female which is approx 5/8" dia, connections spaced approx. 1/2 cm apart in sguare pattern. I have pics. This is for a 28v mil coax switch ('50s?) I would like to use for remote antenna selection. Any help appreciated.
