This is the thread I started a couple of weeka ago : http://glocktalk.com/forums/showthread.php?t=1271548 Some of you wanted an update. My Father-in-law sent an E-mail and the photos that I took to Colt. This is the reply he got today: "From the pictures you have submitted, this does appear to be a Colt Walker Revolver. Although, I am a little suspicious of the address marking on the top of the barrel as it is missing the dash mark between "New-York", I still feel you should consider getting the gun evaluated and appraised..I can suggest a Mr. Herb Glass, Jr. in New York or a Mr. John Gangel in California. Either of them would be a good person to have evaluate it. Unfortunately, we cannot offer research services or a documentation letter on this piece as the records did not survive. So, getting an appraisal would be the next best thing. I can also send you a excerpt on the Walker model from "The Book of Colt Firearms" by R.L. Wilson that will give you general background information on the model, the markings and the characteristics of the revolver." If you would like this information, please let me know and I will have a copy made and get it into the mail for you. Sorry we cannot offer you more on this. Regards, Beverly Haynes Colt Historian My Father-in-law say's that the dash between New & York is there. It just can't be seen in the photos. I told him I can get some better photos for him and then E-mail the recomended appraisers and see what they have to say. I Googled the appraisers and it looks pretty easy to contact either one. Has anybody heard of or had any experiences with either of these two fellows? So, the story continues, and it's getting pretty interesting! I'll post anything else I find out.
