I bought a load of engineering stuff yesterday (mostly BSF taps and dies, drills, files and wad punches; it was in a nice box. Included in it were these four items. They are about 1.25" dia, they look like tool steel and there are no markings. My first thought was "blank dies" but the holes are not accurately central and the edges are milled. Anyone got any ideas?
The pencil was in the box, it is unused and has never been sharpened, if it is of any interest to anyone, I'll happily send it over.

Unusual thread

I know this is lathe-related but it's really just a metalwork problem.Can any one help with this:

I've just broken the nut on the cross-slide feed screw of my lathe; it's a 1920s Erlich, badged IXL, identical to the pale blue machine at the bottom of this page:

The original part was cast iron and has cracked into three. The thread is
7/16 11tpi Whit. Left-hand. The preferred spec for this dia. is 14tpi and taps for this are available, however...
I've brazed the old one together and it seems to be ok but I doubt it's going to last for ever!

I assume it was made this way
