I had a couple of these units in 1972, a electronic shop was selling them off in forest gate. its an intercom/dialer unit no ic's it uses transistors wired as flip flops as counters. you can dial out via the keys 0-9 one digit at a time or use the key switch which then used a pre programmed number. the patch panel number was stored by wires that were screwed to a patch panel. the case was a thick slab of real wood. I think it was intended for use in an office working to a pabx rather than to a exchange line.
