I FIGURED IT OUT!!!
SOLVED(6/14/17)

The mill on page 1 of this thread is a Jefferson Milling Machine. I found it by chance when I was looking at some pictures to make my own dividing head. Here is the photo I found and looked all over that website with no mention of the milling machine. I took a glance at the url and saw the word jefferson. Typed that in and VOILA!! Also, found two other images from another forum of the same machine. According to the unnamed forum member, it uses a 1C collet.
 
It looks like a Jefferson bench mill. I have a Jefferson mounted on a cast iron base/cabinet . The motor is mounted on the inside the case with the pulley pointing rearward therefore it needs an open frame motor like some older washing machine motors. My Jefferson uses the Cincinnati Monoset collets.

Hello @tew45
Thanks for posting!
I have never heard of a Jefferson mill, and there's almost nothing on "the net" that I could find.
Could you provide a couple pictures of yours?
Thanks,

@tew45,
Hey yeah, those are nearly identical.
Thanks!

Here is my Jefferson with a couple of Monoset collets the collet on the right is for another application. When I can I will photograph the motor. A standard frame motor would not fit into the hollow place reserved for it in the rear of the unit. I thought I had a white elephant until I remembered an open frame 1/2 hp motor was used on some washing machines. I pulled one out of an old washer and it fit perfectly. I am truing to come up with a vertical unit but no luck so far. I have been using it as a vertical machine by mounting an end mill in the collet. This methods works but leaves a lot to be desired. There aren't many of these mills around and so far TD's is the third one I have seen. It is a very sturdy machine even with its size limitations.
 
Tew45, I believe it was your pic that I saw on another forum and confirmed what I had found. Can you provide a little more detail about the taper, pics of that power feed, anything really. Measurements of the taper would be MOST APPRECIATED.

I too converted the Jefferson to vertical mill(YouTube video coming in two weeks), without making any permanent changes to the machine. Either my Leeson 1hp motor is not enough or I'm expecting more from the machine
It doesn't have my trust when compared to the Atlas using the same sized cutter. Of course, the Atlas has backgears and my Jefferson is a variable DC motor directly driven by a single belt.
 
It's been a while, but this is my journey through the conversion of the Jefferson mill to a vertical milling machine.

Let me know what you think.
 
I think... I would cut the slot with a hacksaw at this point.

Actually, I am another happy owner of a Jefferson mill. Mine also has a bastardized motor-belt drive setup. Someone also installed a 10 pitch leadscrew on the y axis but left the original dial. Or was it 8 pitch; whatever, they don't match. Took me a while to figure out what was going on. Thought the arbor was flexing or something.

Looking forward to the rest of your build.
