have the schematic for the 701 and 711 PBX; these are somewhat overkill for this application. What smaller non-electronic systems were ever available? Should I consider a homebrew system using strowger relays or a small x-bar, glued together with perhaps silver-wire (more modern) relays?
I have seen auction listings and catalogs of parts salvaged from SxS systems which seem to be quite steeply priced. Is this for some inflated collector's market?

Probably most telcos had displays/exhibits made of 1 SxS components. They were big heavy things, usually having four SxS switches and with their own power supplies and ringing generators. They were bulky things which usually had to be moved around by moving and warehousing companies and shipped by truck line.
