A gun collector identified it as an equally rare F19 1988 single shot
I don't know it has 4 brass bands so I think its an MC010, you decide
.
BOLT ACTION, THERE IS A BOLT ACTION FOR THE PELLET
AND BELOW IT IS THE PULL LEVER THAT CHARGES THE SHOT
YOU LOAD IT WITH THE BRASS BOLT ACTION,
THEN COCK THE SMALL LEVER BACK
AND
AS YOU PULL THE TRIGGER THE SMALL LEVER GOES FORWARD.
This was the precursor to the Falcon FN19 (only better) and is quite a collectable rifle.
These guns revolutionised PCP airgunning using John Bowketts regulator system, meaning consistent power shot after shot.
This one is scruffy with a few holes drilled in for slings and a gouge, see pics.
BUT IT SHOOTS GREAT AND HOLDS THE AIR (SEALS ALL GOOD).
PARKER HALE MODERATOR ON IT.
FITTED WITH a no make but looks like an old Tasco 3-9x40 scope
