Got my self a working Airsporter with mounts and a decent scope for 130 pounds from local gun shop.
Looked up serial number GI its a 1969-1971 model according to guide
Shooting 6.7 FTLB with H and N field but 8.7 FTLB with a lighter pellet
Looks ok fires . I am going to make it a bit of a project , the guns in fair condition, bluing/Blacking is pretty good , no open sights on rear, stock finish ok but a bit scuffed here and there
I am going to do following

Fit a welsh Willy tune kit
Clean up piston and cylinder
Strip stock use a stain and then Lineseed oil finish the stock
and set power to around 9-10 FTLB
Remove butt pad , keep it but fit a adjustable but pad so the scope lines up properly as it will be a plinker/ hunter once done

Any other suggestions ?

Just wondered if any one knew best way to remove butt pad mine seems to be stuck on with no screws etc showing , my other option is to fit a comb raiser
