The lathe is an earlier restoration project I took on last winter. It's a 1922 South Bend Model 25Y. It has a 9" swing and uses changes gears rather than a quick change gearbox to adjust feed rates and for thread cutting. It has minimal wear and works like a charm.
Hand guard ears - it's easy to see how these little fingers could get damaged or snapped right off. When stocking up this rifle I made sure that the front ears weren't touching the rear sight mount and the ends of the front ears did not touch the rear ears. It was also tricky to get clearance for the rear guard clips to clear the stock. BTW - animal glue is still used these days, especially in instrument construction and restoration.
