[Milsurplus] ganged remote for ART-13 & ARR-15?

[Marty Reynolds]

I beleive someone recently mentioned there was a simple interconnect between
ART-13's C-87 control box and the ARR-15.

Looking at all three, the 'simple interconnect,' eludes me.

I do have a unidentified apparrent 10-channel remote box with one
remaining 26 pin socket.  Mighty munged.  Looks like it once held 2
of same 26 pin sockets.  Was that thing once the ganged-control rosetta
stone?

Any tips?

   Thanks
