Looking at 97Bs on gunbroker I note that some have a serial number that begins with "C" and others begin with "D". Both had the number "19" noted on the right side of the barrel just in front of the ejection port.
Anyone have a clue as to what the C and/or D might indicate? It seems as though the ones with the "D" the asking price is about $50 more. Makes me wonder if the "D" serial numbers might be more desirable for some reason.
Thanks
