Somewhere above I saw a statement that the BSRs sold surplus after WW2 were proofed by the military before sale. Not so, many were bought by US & other dealers outside Britain and did not require any proofing as they were not going to be sold in Britain. The surplus guns bought be British dealers did require British proof to be sold in Britain. ( S&W Trivia: Off the subject a bit, but in the 80s when Clinton put a ban on imports of military guns, one of my families companies had containers of surplus Victory models bought from Israel on the docks in Cairo. Can we import ? Clinton says "No', only Police Weapons are allowed to be imported. So, with the help of some people at S&W, Clinton's people were told that these Victory Models were surplus Israeli Police guns. Bingo! Into the US they came and Victory collectors got to add an Israeli Police Victory to their collection ! ) Ed.
