Every day is a School Day! I have been doing the job for 30+ years and now own my own Electrical Contracting Company [previously worked for my family business]...I have NEVER seen one of those and we have worked on some 'weird stuff'!!

Suppose it is the forerunner of the Honeywell CH wiring centre...just a plastic box with choc-block in it. On a slight tangent....is it still contra to the regs to use poly [polyethyl] ene choc block? Cannot remember the reg exactly but it goes something like....all cable joints should be equivalent to, or better than, the cables being joined regarding temp withstand, insulation etc. Poly choc block has a lower melting point than the PVC or Nylon 66 version. There again, none of these can be used in Churches and we have to use porcelain connectors with brass screws. Then when we go to do an inspection it fails and we have to explain why as it is usually one of the congregation who has 'helped them out'. [Linked Image]
