GG, you're in luck! I had an old hand grinder still in the original box that I got 'somewhere' along the line. It's been sitting in a cabinet for who-knows-how-long! I just checked and it's a model 303 with instructions. If you'll give me a couple of days, I'll get the pages scanned in and sent to you. Please PM me with your email address and I'll get you the manual soon as I can!
