For sale, Record SC4 plain body chuck and set of 50mm jaws. Both are brand new, never used, chuck still in packing grease. Together as a package deal, I won't separate. No threaded adapter. The chuck didn't come with the wrench, but I'll include the allen wrench that fits it that I was going to use with it.
