Functional Notes:

Machine was purchased by present owner about 3 years ago. Partially rebuilt, ways and table bed scraped; hydraulic cylinder rod and seals replaced.

Two items worth note: (1) the automatic wheel dresser has been removed in favor of single-point dresser off the magnet; (2) the cross-feed scale is not reading; this may require fixing or replacement. Vertical movement and all other features are working well.

Machine is presently under power and can be demonstrated for serious inquiry.
