It has those familiar RS type "TESTED" stickers which I have never seen on American equipment. One of the stickers is dated 21/03/79 which leads me to believe it is certainly European. Also some of the TI 74LS chips are marked UK.

The 5-pin DIN (240°) pin-out is the same, except here the shield pin serves to supply the -12v supply.

The chap I bought it from did mention it came from the GPO, although a production environment not a development one.
