Ive seen a few bodges in my time. Like the Sharp Ace whoes owner filed flats on top of the barrel so normal mounts would fit.
I did hear of one customer who, on wanting the change the spring in a WH77 but didn't see the joint near the trigger, ground out the retaining pins in the front part of the cylinder and changed if from the front end !!
The nutter who filed a slot in the top of a Webley Hawk and used a modified piston to fire rim fire cartridges in the barrel.
And again with the S & P Galaxy air cartridge system. The owner had modified the original cartridges to the extent that the bolt occasionally blew out backwards. To counter this he knocked a 6 inch nail into the stock behind the bolt.
The Sharp Innova that had the exhaust valve blocked off and the owner had pumped so much the pump arm was 'S' shaped.
The Daystate Midas (brass cylinder) whoes owner had engraved his name deep into the air cylinder.
The owner who drilled the stock of his Daystate to accept a stock screw and, yes, youve guessed it - he didn;t take it out of the stock and ended up damaging the air cylinder.
