Looking for info on Cincinnati No.2 with Bridgeport

Hi all... I have an old Cincinnati that I really don't know much about and am considering selling it to make some room in the shop. I've had it for about 20 years and use it occasionally for odds and ends, but I'm no machinist and it's more of a waste of space at this point. I'm trying to learn more about it to properly list the thing; What exactly is it, how to describe it correctly, value? I sold some other equipment to a guy who said it has some value because it's a horizontal machine that a vertical milling head can be (and is) mounted on, which I understand but not sure how to denote this. When I look up Cincinnati No. 2 I see a whole lot of mills that seem to have a different top section, not sure why this one is different.

Anyway, any info I could learn from would be great!!

Looks to me like an old Cincinnati mill (maybe around early 1930s to later 1930s???) that someone has adapted an older Bridgeport head to mount on it. I did the same thing with my 1935 Brown and Sharpe 2B horizontal mill. I made a mounting plate and mounted a Bridgeport M head on it. Not sure what Bridgeport head that has on it, but people will probably want to know what taper the spindle has. Do you know what tool holders it takes or do you have a picture you can post?

Thanks for the info. I have a bunch of collets that are all listed as "R8" regardless of size. Is that the spindle taper?

Yep, that's an R8 spindle. Is there any tag on the head to help determine exactly what it is? If it has a serial number, that my start with some letters that my be a clue. My M head has a morse taper #2 spindle. I think there are some M heads with a B&S taper as well. That my be an early J head. Not sure, maybe someone else can jump in and help. Buyers would also want to know what voltage it's running on as in 3-phase or single phase.

Too bad it has a single round overarm.............otherwise, I kind of like it.

IIRC, the M head was #7 B&S

Yes there's a tag, but no serial number, not stamped. Doesn't seem to have any sort of identification on it really. The mount does't look entirely homemade, but who knows. The head is single phase, i have it on 220. Any idea of weight??

I seem to have a bunch of what I think is Morse taper stuff too, don't know why there would be both.

The mill itself is from the early to mid twenties, and the horizontal spindle will have a 14 B&S taper with flanged spindle

Thumbnails from 1923 on the 1M - the otherwise identical 2M had 6" more table travel

Cool, thanks for posting that! Had a hard time finding anything useful so far.
