A small correction to my earlier posting. 

The Crossbar system we're restoring is a 756-A, not a 756-AN as I originally mentioned. The 756-AN used different connectors. 

We're in need of KS-14173 connectors for a 756-A system.

Hi GreenKeyers;

I know this is a long-shot, but I thought perhaps the GreenKeys teletype community might be able to assist. 

I'm working with an ex-Nortel gentleman who is in the process of rebuilding a 756-AN Crossbar PBX switching system. The system depends on a "crown cable" to tie together the equipment slides within and between cabinets and such a cable uses KS-14173 connectors (jacks) and KS-14160 connectors (plugs). These were connectors for telephony equipment of the era, and may have even been used in some teletypes. 

We're looking for some KS-14173 connectors (quite a few). For those not familiar with what they look like, the attached drawing and photograph show them. In the event the attachments are not preserved, they can be seen on the first page of this BSP document:

Any leads on someone with a box of these gathering dust, or even an existing "crown cable" would be incredibly welcome!
