The "FB RECORD JUMBO" was producer from 1982-1997 according to the BLUE BOOK. It is a great and unique design as it has a oval piston with rifled barrel through the middle. I think the pistol is great fun and accurate for its compact size. I don't think they go for much as there seem to be a lot about I paid £60 for mine in great nick but with no box but then seen 2 boxed versions for the same. Definitely worth a go as they will get harder to find. I was also warned that they are hard to strip and so far haven't tried.
