Thought maybe Roger or someone might be able to ID the engraver or provide anny info for the owner of this Colt. As the letter states, Colt was unable to provide any info. I told him to check under the grip for any signature or makers mark.
The image is far too small for me to make any attempt at attribution. I can, however, see enough of the left panel to tell that that part is not by any gun engraver that I am familiar with.
