I am going through my late grandfather's 1946 (approx.) Craftsman lathe. it is pretty much complete. There is no serial number tag on it anywhere. The counter shaft does not mount to the body of the lathe. It is designed to mount on the stand or table that the lathe is mounted to. It has the bushing for the spindle in the head stock. Is the non-existent serial number any indication of its date(s) of manufacture? I have recently obtained another 6 inch Craftsman lathe. This one has the actual bearing in in the head stock. I would really appreciate any info that can be shared.
