Bought this at an auction liquidating local machine shop
It was with some stuff in duplomatic packaging this is not labeled so have no idea brand,
I AM NOT FAMILIAR WITH MACHINIST ITEMS so don't know how to correctly describe this item

Lots of pictures
dial readout allows for 1" travel lock collar missing bolt
No hold down bolt / head
Thank you
Selling as it is
Feels as if had very little use seem tight and right to me.
