Does anyone know what serial number tells you the year of the head on a bridgeport series1 mill?
There is a plate on the side of the variable speed head that says DRIVE SERIAL# 2JB S2163
And on the front it has stamped JB35521 or JBB5521 im not sure if the third letter is a B or a 3. It is a 2hp variable speed head.
Thanks Mike
