Unfortunately, the engraved RM isn't signed. It was shipped to Binghamton, NY in the height of the depression. During that time there were plenty of folks in upstate New York with the wherewithal to afford such an extravagance.

Edwin Link was developing his pilot trainer there in the '30's. Thomas Watson had just recently changed the name of his time clock company to one that you may have heard of...IBM. Johnson Shoe company was soon to be delivering in excess of 50 million pairs of shoes a year from their plants there. Roy McHenry, of McHenry and Roper author fame, was establishing the Binghamton Rifle and Pistol Club, and of course, the Manhattan Cosa Nostra were taking their retreats there.

Relating all of that to the RM is nothing more than wishful thinking with out a specific tie and unfortunately, I don't have one.
