The two side plates were broken so I used the side plates from my mint pistol to make mini moulds out of plasticine and used araldite to caste/fix the missing bits, re drilling and countersinking the screw holes. The grip had been near some sort of heat and was distorted so the base plate had gone missing - more araldite and an artistic application of files etc before a spray base and top coat. All the plastic bits were polished to get rid of scratches, the rest I had nickle plated. The internals were given the full replacement etc treatment.
