Guys I was going to start on my Colchester lathe(headstock alignment) but I just discover that the chuck has aluminum jaws that has ridges turned in it for some reason.So I need to order myself a new set of jaws but I can't find a brand on the chuck other than #2083 I look on the side of the chuck,look on the back plate found nothing.Not anything on the jaws either so I am at a loss.If someone could take alook at the pics and see if maybe they can tell what I need?Thanks guys----kroll
