I've just took posession of a new (to me) Jones and Shipman 540P surface Grinder and I'm trying to figure out when it was built. I've gone over the information on lathes.co.uk and I believe I've narrowed it down to somewhere in the 1965-1970's based on the front control panel and the HP rating of the hydraulic pump motor (the pump motor was upgraded to .75hp in the late 60's)
Anyone have any information on what the serial number will tell you bout the date of manufacture?
The serial number is 72393
At a guess this could be the 393rd machine made in 1972.
