N/A Break barrel identification please

[Houli]

Gentlemen,
A friend of mine has an air rifle torn apart and looking for a brand or model but can't seem to fine any identification. Anyone recognize it from the pictures, or care to take a stab at it.

Thanks

HATSAN MADE Winchester 800 or 1000. They are 27 mm tubed guns with AWFUL TRIGGERS. IT WAS Hatsans early foray into air rifles.
