identifying a Bridgeport

i'm sure this has come up before, so i apologize in advance. but i've checked the web, the dropbox, and even searched old messages.. and have ended up here.

i've come across an Bridgeport Knee-style mill. all manual, with X and Y DROs. i'm trying to get an idea of when it was made (ie, how old it is) and if i can find a manual for it.

here are the numbers i pulled from it:

the head: Serial #: JB26783

the body (left side): Order #: 61421 S/N: 2775105784

on the knee casting: (a website instructed me to push the table back to unveil this number) all it said was: 013 the "0" looked more like a backward "D"

the motor says: HP 1 2 i dont know if these means 1 or 2 HP or 1/2

it has two speeds on the dial: 2 forward, 2 reverse step pulleys power downfeed (though i cant figure out how to make it work!) oiling system has a little handpump on the left and a bunch of those little fliptop oilcups

much appreciate any help or links to where i can find this info and (hopefully) a manual (electronic is fine)

thanks!
