Made a back plate to adapt it to my 1959 Edgewick MK1 lathe.
Once in place had about 0.0015 run out, mostly from the lathe it's self.
The jaws were not perfectly alined but easy fix ran boring bar through centre with carbide insert.

The jaws can be put in any slot as long as you pay attention to where the teeth catch. Only other thing I would say is that I have been having to take the jaws out after each use to clean out chips. Jaws stick if I don't do that. Value for money you could not beet it. Might buy one of the smaller one's to fit in to tail stalk with morse taper 3 and back plate to suit.
