I bought this 66 block off eBay today assuming it was for a 37 station intercom like the Melco KR-37. However, the last pair (H/INH) was throwing me a bit and after some Internet research I came across a Valcom product (V-136HRTF) which is a hands free, talk back intercom/paging system with speaker inhibit (INH, eh?).

But even then, nothing really lines up. I guess I'll just have to wait until it arrives to see how the Amphenols on the side are wired.

In the meantime, anyone seen/installed one of these before?
