Pre-war Webley&Scott MkIi straight grip

I have this really nice little hard to find Pre-War ( 1925-1930) Webley and Scott MkII  airgun in 177 cal.  It does crank but piston does not hold back. i believe is the trigger return spring that does not push the trigger all the way back to catch and hold the piston back.  It also miss the rear sight and a few screws. Beside that its completel, finish is nice and there is no rust Definitely worth fixing . The grips are damages at the heel but this is an easy fix ( I can fix them for few extra bucks) .

I am asking $250 . its Located in Limoges, ON ( about 25 min drive South East of Ottawa on Highway 417 .  i would prefer local sale but I will ship on your dime if needed .
