We don't know of a lathe sold by Sears with a model number of 101.07001. The closest valid number is 101.07301, made from 1939 through 1957, This was made by Atlas. It is a 6x18 size lathe with 16 speeds, 8 in direct drive and 8 in back gear. It has sleeve spindle bearings, and 1"-8 spindle threads. Except for the spindle, bearings, headstock casting and legs, most of the other parts were originally the same as those used on the Atlas 618, another 6x18 which came out in 1936. If your machine is a 101.07301, the serial number should be on the right end of the front way.
