I purchased a Harrison L5A 11 inch which came with these change wheels that are for another lathe. I would be grateful for help identifying what they fit so I can sell them and the proceeds go towards obtaining some of the right ones. There's a total of 6, Teeth 55, 60, 65, 70, 75 and 100. 3/4 inch bore, 1/2 inch wide, 1/8 inch keyway. The cast ones have a L4 marking and what looks like 88 or 86 but could be just be marks from the runner or raiser.
