"t appears to be a low numbered model? considered 'dangerous'? "
One note that I left off my original post: I have one also, made in 1905 - I shoot mine. I've looked deeply into lot and production numbers to get a sense of when and in which lots the failures occurred and how they happened. I'm satisfied that the one that I have is one of the many single heat treated receivers that are safe. A personal judgment, I know.
