I have a nice little Zeiss Ikon 521 6x4.5 with a novar 75mm/f6.3 in a Klio shutter that has a sync connector I’m unfamiliar with and trying to find any details about it. This camera was at the bottom of a junk box of other photo stuff I picked up at an estate auction and miraculously has no light leaks and works great after a little shutter cleaning.

This copy has a star in the serial number which i understand to mean it was assembled postwar with prewar parts - so probably mid-late 40’s vintage?

the outer barrel of the connector is 3.8mm, too big for a standard PC connector. any clue what size/type of connector might fit? I’d love get/make a PC adapter for this guy so I can flash with it.
