Hi Joe,
Thanks for all the great information. I didn't see any "L-M-R" lever on the machine. Also, there are a ton more pics on my blog if you click on the link. Maybe they will be helpful. I would love to find a manual but I think I need to figure out the model number first. I also posted about it in the Yahoo group but I'm not sure that anyone responded. Or maybe I am just not getting responses to my email.
