This was my Grandfather's work machine at a defense contractor in VA that he worked for for 30+ years. When he retired in the early 80's he got to keep the machine.

The custom Tool post was my grandfather's shop made tool he designed and built for work.

It uses Hardinge 3C collets in the head stock, but I have no idea what to call the tailstock collets. They have a 10mm x 1mm pitch screw thread on the back of a Hardinge style collet; but the collets themselves are in inch-sizes.
