[ARC5] Connector question.

[telegrapher at att.net]

Whilst sorting through my command set connectors i found the following.

An 8 pin connector like the PL-152A that has the markings MX-2/ARR-2 on 
the cap which covers the place where the wires are supposed to come out 
the back of it.  On the side of the body it says: CZR30617-1.  ANyone 
know where this might have been used?  Sounds like it took the place of 
a PL-152A on the back of the receiver rack when an ARR-2 was installed. 
  I better not say that was actually the case until i hear from the 
experts here.

I found another one that is marked on the barrell: B-41725, PL-152A, 
9125.  I understand the last two numbers but is the first one some sort 
of inc. company id?

A third connector, PL-152A type shows CZR-696451 on the barrel.  I 
wonder if these were for a particular installation or just one of the 
military odd numbering system gizmo's?
