Buzz, did you go forward with replacing the duck with a grouse on your gun?
I'm coming back to this thread after getting my 16 ga. M-21 back from Ray Cover. Ray was among the engravers featured in his book that Roger Bleile particularly recommended in this thread. Roger's book led me to contact Ray and a few others to assess their interest in my modest project -- a remembrance of my best springer spaniel, who went suddenly blind of SARDS at age eight.
Ray worked from a few photos of Abby, along with grouse, pheasant and feather images I sent him. To say I'm pleased with his work is an understatement. This is the gun I usually carried when hunting over Abby. I've liked seeing her there when out with it this fall.
Mark Beasland polished the frame and re-rust blued the barrels. Art Isaacson blued the frame. I'll soon get the hinge pin screw alignment back to horizontal.
Forgive the amateur photo quality, I have only an inexpensive autofocus and not much clue of how to use it.
