Hello All: I broke my favorite non-marring hammer face and need to make a replacement insert as this company is long gone. The original was turned from a hard non shattering white material about 5/8" in diameter and about 5/8" long. Any suggestions as to what material would work best for this application and a good source for it? Also, I'm working on a Forehand and Wadsworth fine twist barrel which needs to be blued/browned. What are the best options for a twist barrel? The same gun has and outside hammer which is missing. I've tried Numrich and searching the web without luck. Anyone know a possible source for the missing hammer? Best, Dan
