I do get many tools coming in so if you are interested in one like this then please do not hesitate to contact me and I can either see if I have another or similar in stock or let you know when one does come in.
Pratt Burnerd lathe chuck, 6 jaws and comes with the reverse jaws as shown.
Another user stock number stamped on the face as well.
Jaws in general very good for a used chuck, no.1 no wobbles at all, the others you can just about feel move but no major wobbles and what you would expect from a used chuck, that being said I don't think this has seen too much use at all.
Main body is 2 13/16" thickness. The bore is 1 3/8". The first recess is 3 3/14" diameter then goes down to 2 5/8"
With a very tatty box it was found in which I have kept with it as seen in last photo.
