Crosman Model-761XL ('Whaley Crosman' custom).
With thanks to Pete for these pics.
This was an ill-fated multi-shot adaptation of the Crosman pump up advertised in the UK around 1980.
Another pristine Crosman 761-XL.

Serial number first three digits: 576 which means May 1976
Bought it from a toy collector dealer who mentioned he had an old airgun new in box, he couldn't remember what it was so he asked me around to his house after hours, it's like that classic car find when you open the garage door to find that mint dream car.
