I am new to working on a lathe and just bought a South Bend 9 C I believe. There is an extra pulley that I have no idea where it fits into the equation. Any help will be greatly appreciated. Also if anyone knows if this is actually a model c or toolmakers 520.

The tag on the gear cover has the catalog number. That's what you got. The 'extra pulley' may not be for the lathe. To run your lathe, you need motor and countershaft and flat belt to connect them to your cone pulley.

See the first dozen pages of this for how your lathe was originally setup. http://vintagemachinery.org/pubs/1617/17260.pdf

Lot's of catalogs an other info here: South Bend Lathe Works - Publication Reprints | VintageMachinery.org

More info here: http://www.lathes.co.uk/southbend/index.html

Here's how mine is set up (see motor and countershaft behind the headstock):

Here a link to the photo of my tag Imgur: The magic of the Internet

I had read that about the catalog number but as you can see from my tag, I have non. Thought this to be odd. I have the serial number and I can date it to around 1934-1935. That's it though. Any other help would be very helpful.

Is it that we can't see the reverse lever or is it that it does not have one - see thumbnail

Thanks to Mr. Wells for the scan - may help

I had to take off all electrical because of the clothe wiring and it's corroded condition. But I do have the switch if that's what you mean. The rear pulley that the motor drives is also odd just as I haven't seen one like it anywhere. As for the link, I actually found that from wswells.com while researching. That is what led me to believe it was a toolmakers lathe. I have the serial number 57098 if that helps. I have seen close to that number and it was a tool makers.

Talking about reverse lever for left end gear train - probably we cannot see it (if it had one) in that photo because of the large gear cover in the way

From Mr. Wells site-

http://www.wswells.com/data/catalog...W/1935March_Revised_edition_Bulletin_No5W.pdf

Be aware of some things that are specific to the model-
Uses 20DP change gears instead of the more common 18DP
Has a left hand acme leadscrew
Has no reverser per se, that is what the gear "going to nowhere" is for, to use it you must lower the banjo and take it off the storage position and install it on the headstock
Most importantly to you is the spindle is likely the 1 3/8"x8 tpi instead of the common 1 1/2"x8
 
Thank you for the help. Upon more research, it is a model 5. That spindle really gives it away too. No my problem is going to be finding a chuck for it. Or I just get a custom back plate
 
While I typed 1 3/8"x8 I should have typed 1 3/8"x10

You will have to make,modify,or have someone make you back plates.

A standard 1"x 10tpi backplate may be bored and rethreaded.

You can watch eBay too, sometimes chucks pop up.

Oh, and that extra pulley thing is your countershaft, and it is very nice that you have that.

There are a few guys that enjoy setting up old line shaft driven shops that I'm sure would like to have the whole kit and caboodle.

that doesn't mean there is money in it though.
