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, 16DP at 100 % confidence, 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 just be marks from the runner or raiser.img_20191224_122852_7.jpg

I agree, the L4 is a common S & B casting / forging mark, and 16DP is one of their gear tooth sizes for the model M type.

Not suitable for your lathe?

If you could cut centres, might it be a better to modify these than buy originals?
