This lathe was originally bought by the US Navy and used in an instrument repair shop at Mare Island, Vallejo, California. It was bought by it's present owner at auction in 2002.
The lathe is equipped with variable speed, lever tailstock, lever collet closer, micrometer carriage stop (missing rod) and the later style "long" cross slide, which incorporated T slots for a rear tool post and an integral taper attachment link bar.
Six position, automatic-indexing bed turret.
Two photos of a radius-turning attachment, which installs on the carriage in place of the cross slide.
