I found out that Hardinge UK (current owner of Bridgeport Machines, LTD) heas a complete maintenance manual , with schematics, for my Bridgeport Series II Interact 2 mill. I called them and they told me that though they have the manual, they could only sell it to a UK customer, and that I havce to contact Hardinge in USA. They do not seem to have it in USA.
The cost is 30 UKP and I can reimburse you for this plus send a little extra, via paypal. I think that they will email you a PDF.
I have all the contact info etc.
Thanks a lot.i
