Description:
11" x 58" Bridgeport Series II Vertical Milling
Machine. Bridgeport Series 2 were basically
custom built machines. They were never put on
an
assembly line, like the Series 1 machines
were.
It is very rare for one of either of the
Series
2's to have been built with errors, blemishes
or
mishaps. With proper care and maintenance as
described in manual, there is seldom need for
service this Bridgeport machine.
