I know that this is one of the first 109-series lathes and I have not been able to get a manual or parts list for this lathe yet myself.
If you are new to metal lathes in general or you would like to have some other information on metal lathes my Lathe Resource CD has a ton of stuff on it. I just had to buy a new scanner and I am working to get a couple new manuals scanned and included but it has dozens of manuals, diagrams, catalogs, and much more...
The CD is now at it's limit and I think I need to move to a 2-CD set soon...
Here is the ordering info... there is MUCH more on the CD then listed on that page!
