Hey guys, picked up a Cincinnati 2L universal mill today. I didn’t know when i I bought it, but it ended up coming with the dividing head and a slotting attachment. Also a whole lot of tooling. Was looking for advice on where to find info on how to set up the dividing head to cut gears. Also what type of tooling is used in the slotting attachment? Am I going to have to just grind my own tooling from HSS blanks?

Nice score! I've got the same mill, but it was bare with no attachments. So far I've got a cincinnati 10" indexer and hope to one day fab up the low lead box and change gears. Please post more as you sort it out.
There's some good videos on YouTube showing how to use a dividing head to cut gears. The gearbox is only used if you're cutting helical gears and would be set up similar to how a lathe cuts threads(such that the gear blank rotates a set ammount as the table moves a set ammount), while you are milling the teeth. With that you would use the swivel table (what makes it a "universal" mill instead of a plain mill) to account for the gear cutter cutting the helical teeth at an angle.

While not a manual for your specific machine this book covers many of the milling and dividing head operations on machines similar to yours
Older Cincinnati publications can be found here.
The videos showing a universal dividing head at work on a K&T machine should be similar enough to give a good idea how to go about the same job on a Cincinnati
you can see the follow ups here
There may be more information or a Manual for your machine on line if you search the Vintage Machinery site.

P.S.
2L and 2ML manual here

A few Cincinnati factory publications might be helpful to you (almost every Cincinnati factory publication was numbered, typically beginning with "M-" and revisions had a numbered suffix, e.g. "-1"):
1. M-1946-1 8"-10"-12"-14" Universal Dividing Heads and Accessory Equipment - Operator's Instruction Book
2. M-1769-1 Cutting Gear Teeth on a Milling Machine
3. M-1454 Universal Dividing Heads and Accessories, Indexing Attachments - Service Manual and Parts List Catalog
4. Catalog ATA-00 Slotting Attachments - Service Manual and Parts List Catalog

And their own "bible" from the later days - not to be confused with the 1916 issue.
A Treatise On Milling and Milling Machines copyright '50s. The original is a big solid book with red cover and very high class paper
The "L" is closely related to the M and here is some of that
DH set up can be seen on page 69 for the 2M as of 1926
Your "K" date code in your serial is 1941
It looks to me like your DH on the left in your photo is K&T Model H
