I've got a 2 b that I'm guessing was made in the mid teens....maybe someone knows how to date it? Single round over arm, power feed on x, y, and z. It's a good old mill, many years left in it. It's a lot more machine than my Bridgeport clone when it comes to heavy milling, that's for sure. Anyway, I'm looking for a universal head for it, if anyone knows of one. Probably scarce as hens teeth. But if someone knows of one, let me know. Thanks.
