RARiddell your suggestion is as good as any though there is still room on the flats at the time of the Birmingham proof also the number of guns with impressed numbers like we have are not that common. On my gun there are the original London view an definitive marks and the Birmingham nitro proof marks and there will still be enough room for re-proof marks at .740 though it will be the next keepers problem to sweat over. My feelings are that the proof houses are not taking in to account the gun making heritage of the UK and seem hell bent to destroy as much of it as possible. It is starting to become ludicrous in the way vintage guns are being destroyed by making them come up to proof levels as if the gun was made last week with modern materials. We do have Ministry of Transport tests for vintage and classic Motor Vehicles, they are not asked to come up to and pass new motor vehicle standards. My personal view of this UK gun proof situation is a little obtuse some would say, though I do feel that because the proof houses have a large input from the gun trade they have the outdated business view the more guns we take out of circulation the more new guns they will sell. And of course if that were true "if Pigs had wings they would be Eagles"
