When I pull up photos of these guns it appears that the complete action is casehardened, as I can see the colors on the action. The photos, however, are not close-up enough for me to be able to tell for certain if the hammers are, but they look to be. If so, it makes me wonder if something like Kasenit will help the problem, and what heating to cherry red will do to the existing colors.

How many rounds does it take to get the hammer peened to the point that it is unusable?
