No it’s not a pinball but a ‘Computer Space Ball’ from 1972 . Was fully working last time it was played.... in 1974. Seems to be a Pong clone, very funky glitter gold fibre glass cab.
Difficult to put a price on that due to it’s rarity but a cracking find it’ll be all TTL and most likely a b&w tv in there too. Can’t be too many people looking for one and I assume it’s going to need a bit of work to get it running so maybe 500 quid but that’s a complete finger in the air guess
