South Bend Lathe serial numbers are stamped on the front tailstock end of the bed, between the flat and V-ways. Records show that lathes were first numbered sequentially, beginning approximately, with number 700, in July 1910. In March of 1947, a new serial number system was introduced which added a three-letter code and a model/series revision.

Identify Your Lathe And It's Parts

The serial number is stamped on the tailstock end of the bed between the flat- and v-ways. It is used to determine the size and type of lathe, plus any special features or attachments. The earliest records show that lathes were numbered sequentially, beginning with 700, in July, 1910, and ending with 186,514 March, 1947.

After that date, a new numbering system added a three letter code to indicate 1) the swing, 2) the gear and apron combination and the location of the drive, and 3) the spindle hole size, type of swing, and special features.

is the 2,345th 10' lathe built. It has quick change gears, friction feed apron, and underneath motor drive, a large spindle hole, and standard swing. The number 7 is the model number, which is changed when modifications are made to the machine that do not change its overall characteristics. Each swing size begins a new numerical series, starting with the number one.

The following factors about the lathe are conveyed in the catalog number because of the infrequency of repaired part orders:

Although the code number of the headstock changes when supplied with a V groove pulley on a 9 inch lathe, or a 3-step cone pulley on the 16 inch lathe, the letter symbol designating the size and type of lathe stays the same, and is made in the model number as shown. Only the unit code stamped on the headstock changes:
