I managed to break my hammer today, a Blacker model C. The lower parallel arm broke, you can see from the oil that had penetrated the initial crack that it has been starting to break over a long period of time, hardly surprising given that the hammer is 70 years old:

I'll fabricate a temporary replacement from strips of flat bar, I'll then forge a new bar. You can't simply use round bar as it tapers considerably. If both arms had busted at the same time it would have been interesting.
