one of those thoings that there really is not known numnbers, ALL the gungoing into britain were proof marked over the years, its HOW Many got out and came back here to the states??? usually a serviceman would bring them back, ,,when my friend Terry helped run the Air Force gun club in England many years ago, they were able to see and could get this kind of stuff to bring back, but seldom Rugers, there was too much other BETTER?? stuff...other European countries also "proof marked" guns coming into their countries,goes back MANY years to the "proof house" rules?? laws?? am not a student of history...........
still a nice find radical, Laura sold off ALL of hers many years ago..........think she may still have a bearcat, came from Europe BUT becasue it was bought at the 'PX" ( US property) not needed to 'proof mark' but had to have ALL the paperwork, green card, etc to bring it home from overseas.........
