I count 6, not including the photo miss-mash at the bottom. Craftsman "80" is some sort of marketing hype, as it doesn't actually appear on the machine. The year before, there was a wood lathe plus an earlier version of the AA metal lathe advertised under Craftsman "80". There was also a Craftsman "100" wood lathe. Sears used to do a lot of that - Companion, Dunlap, Master Craftsman, Craftsman Deluxe, etc. Those terms aren't usually useful or accurate for ID'ing a piece of equipment. Prior to about 1951, the Model Number plus the Catalog Number both might be required in order to accurately ID a machine. From at least 1951 on, the Model Number became unique, but they did not make the change retroactive. The 101.07403, for example, always required knowledge of the Catalog Number if you were ordering certain parts.
