As luck would have it, I only found the box mount male receptacle in my stash which is what you already have.   The mating female connector that you need is MIA. 

I checked my WW2 era  Amphenol catalog # A-1, the contact pattern is 28-8 which you should see
28-8PF embossed in micro print in the phenolic base between the two widely spaced pins on your example.   P is for pin, F is for, I assume, flange.

If you want a straight connector, that would be AN 3106-28-8S.
The angle version would be AN 3108-28-8S.

Regards,
Jim

Would like to help but I have no idea which connector you need.  I have acquired quite a few connectors over the years but I have no idea what equipment they came from.  A photo of the mating connector would help.

Thanks Jim, better pics here.  Its a 12 pin thing.
