I have logged 3 similar revolvers, all within the same serial number range, with the same markings. Of the 3, the only one I know of with a letter shows a shipment of 6 to Evaluators, LTD. in Quantico, VA. Many of you will recognize that outfit as the one run by BG Van Orden and his wife Flora. They had close ties to the USMC and sold lots of guns to them. I don't think this will letter as a factory marking. Perhaps Evaluators marked them. I suspect these guns were for the USMC shooting team and perhaps the Marine Corps armorer marked them. Whatever the case they are interesting guns and I hope Mr. Warren reports back what his letter shows when he gets it. Here is a picture of a similar gun (not mine).
