Many thanks Simon,

I have since had some recent information that the rifle was "assembled" at York Guns from original parts but whether the parts were bought up from Charnwood when they closed or supplied at an earlier date can only be surmised. I know that York guns had several Singapore Swedishicon Mauser CG 63 origin sniper rifles quite a few years ago and wondered if there was any connection as serial numbers of Enforcers close to the number on mine have been identified as going to that part of the world.

Thanks again
