Hello. I am fairly new to this forum. I am inquiring to see if anyone out there can tell me more about a 1st Generation Colt SAA marked "E.S.K.". I believe it stands for "Edward S. Keith" dectective and guard, Denver, Colorado. Does anyone out there have any inofrmation on the "E.S.K." Colts or can anyone direct me where to find more information? Of course, I will be contacting the Colt Archive Service for a letter. I appreciate any assistance and information that can be provided. Thank you in advance for your knowledge.
