Well, as the other posters have said, you have a 319. Now you will just have to go get a model 66 to go with your manual :wink: :-D No sense letting that manual go to waste! :mrgreen:
Here is a cute YouTube video showing a 319 converted to work in a treadle cabinet:

After watching that video I added a 319 to my "wish list". I found one on Craigslist a couple of months ago!!
