I am looking for information on a set of Colt .22 cal "lord and lady" derringers. They are not mine and I don't have a lot of information on them. I am researching for a friend. Here is a pic
The barrels are stamped .22 cal short Colt Hartford Ct USA the wooden grip serial # 50517der and the pearl grip serial # 50518der. From what I have found about the serial numbers, they were shipped from colt in 1976. Does anyone know what the value of these guns would be?
Any help or information would be much appreciated
NOTE: There is only one set. It is just two different pics of the same set
