Bridgeport J-head mill, serial #12/BR 48763 which makes it a Series 1 manufactured in 1960.
Here's the back story. My brother was at an auction 2 years ago buying 2 BIG ASS fans and while there, he saw a pair of mills for sale as well. He called me and asked if I was interested. I was but skeptical of auction items, but they were under power and shown working so I told him to buy one for me. I've had it stored ever since because my building doesn't have the electrical capacity to run it. I'm selling off a bunch of stuff and it's time to get rid of it and try to find a small single phase bench top mill. This is a 3-phase unit, so everyone knows. I'll get the motor spec's and some additional pictures and post them tomorrow.
