Earlier this year, I successfully bid on this tool.  The Seller let me 'back out' of the deal when I realized and explained that the tool was not correct.  I believe it was made from a 1903 Springfield tool.  The drift pin is too long and points the 'wrong' way.  The "US" mark is also not the correct style of lettering and there seems to be more metal surrounding the rivet at the top end of the tool.
