Elephant Ivory Mammoth Ivory Mammoth molar (no dye) Mother of pearl Walrus ivory Burly Ironwood or similar other suggestions? The elephant ivory may be difficult to find so I am not holding my breath on that one. as far as the finish on the metal I like nickel plating (hard chrome? or even a high polished stainless steel) but wouldn't be opposed to a color case hardened frame with a blued barrel done by the likes of Turnbull. The firearms I have on hand that I am considering are these, all are in great mechanical condition, none have any sentimental value; S&W 29-2 blue 8 3/8"- its in really nice shape save for a couple very minor cosmetic flaws S&W 57 no dash Blue 6" also in very nice shape virtually no cosmetic flaws. S&W 27-2 blue 6" this one is rough, it came with some beat up magna grips which I replaced with some cheap rosewood target grips but some of the bluing is missing from holster wear dings ect.. Colt Python 6" 2020 version stainless steel perfect condition. Magnum Research BFR 475 Linebaugh stainless steel 7" has buffalo horn grips and some very light scratches on the cylinder and ejector rod housing. Ruger Blackhawk 3 screw 4 3/4" Blue 357 magnum has some dings and scuff also unfortunately has the "safety" conversion. Dan Wesson 357 super mag blue 8" perfect except for flame cutting on the top strap (not my doing, on a side note, any one know if this is correctable?) S&W 686 ( -4 I think, before the dreaded Hillary hole) 6" stanless steel 7 round in pretty good shape. S&W 629-5 5" classic full underlug round butt. this one is in pretty good shape except for a couple small dings on the cylinder and has the wrong screw holding the rear sight on. Ruger Vaquero stainless 4" 45 colt birds head grips, in great shape Some other options I am considering buying for this cause; Colt SAA in 45 Colt 5.5" S&W 25 in 45 Colt, pinned and recessed 4" 5" or 6" barrel, though I tend to think 4" might be a little short for this project. I would probably look for one thats like the model 27 rough looking but mechanically sound. I am also open to other suggestions for the donor gun. I like the 5" and 6" length barrels for this, I do think the 8"s are a bit long. I am currently leaning in the direction of the model 57, or a model 25, with either the mammoth ivory grips or mother of pearl. But I am definitely open to suggestions and input and reasons why. It will be fun to make my own leather to match. If pics are needed I will edit later and add them.
