I'm looking for a crossbar switch, like the 755, myself.  If anyone has one
to sell, please email me off list.

Frank,

I had a chance to buy two crossbar switches a couple of years ago and 
had them shipped out from a collector in New Jersey. I have one of them 
(a Western Electric SS400) on CNET, and the other (a WE 755) is 
available for sale. It cost me about $2,700 including shipping and 
you're welcome to it for that, loaded on your truck in Santa Cruz. It's 
in a single rack "tombstone" cabinet with covers and a roll-around base. 
It weighs about 600 pounds, see photos at 
http://www.telcomhistory.org/vm/exhibitsSeattle6.shtml and 
http://www.telephonecollectors.org/events/lnc2005/lnc.htm . It's more of 
a PAX than a PABX in that it doesn't have trunks that can be routed to 
non-key extensions but it handles 20 lines through 3 links, and 4 
incoming trunks on a sort of early key system approach using key phones. 
There is a "transfer" function that allows CO trunk calls to be 
transferred from key stations to non-key stations -- it is wired for 
that but lacks the relay that's required to make this happen. Full docs 
are included on how to do that. It works fine and includes copies of all 
relevant practices and the original envelopes of SD drawings.
