Down your way Devon ish or Cornish there was a guy doing bling polishing of airguns esp Co2 called ' BigDog ' or similar .
He did repairs and servicing too I think . He had to disamantle the things to get them polished so makes sense he rebuilt them .
Had a small website from memory and think he was here as a member here for while ?
