Dwight,
I agree with all you say...
But the British proofs are an indication of some 'safety checks' performed on the gun before it was allowed to be sold in England.
Our import marks are just that; an inventory mark of which vendor happened to bring it into the USA. No implicit statement for the gun's condition or its safety...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
