Hey Smilin,
I don't have a manual for the Lyman Acculine hand/bench tool, but I do have one, and I may be able to answer questions for you about it. It seems they stopped making them some years ago, and it would also seem they did not make them for too many years. I don't know why they would not have been a decent seller for them. They still make the Lyman 310 Nutcracker hand tool and special dies for them. I also have several Nutcrackers and a few die sets which are pretty neat to show folks how you can reload shells while sitting on the tailgate of your truck. However, the Acculine uses regular shell holders and regular dies and is less work to full length resize than the Nutcracker which only neck sizes.
Let me know if I can help you.'
Best wishes,
Dave Wile
