shawn: it is nice to hear from you. it sounds like you know what you are doing? but, you too seem to have a mind set that will not accept the fact that old ed does NOT use a torch in his receiver coloring process... as for green colors, they are typical of some ithaca and fox guns produced during the 20's and 30's. old ed has duplicated those colors as well...how many sxs shotgun receivers have you rehardening via the high heat, bone charcoal method? can you refer us to any pictures of examples of your work? have you ever damaged a receiver beyond repair? have you ever had a receiver crack after firing? what is your guarantee, if your customer is not satisfied with your work?
