This weekend past I bought an old (ish) BSA Airsporter. More for sentimental reasons than anything else. Rust has chewed into the smooth surface over the years, and it?s probably shooting at about 400 fps. I need to have it re-blued, and get some of the internals replaced, however I?ve ended up in an a few heated arguments with a couple of gunsmiths in my life insofar as bad workmanship is concerned. Can anyone refer someone reputable on the South/East Rand?
