Jeff,
I will look if not my friend in fl, rich at rms vintage, who does stoners and nationals a lot, will tell me how to do it
If there is a section on how to adjust the coin mechanism for different prices, I wouldn't mind a scan of that page or pages. My price wheel goes from 15c to 35c, or somewhere in that range. Right now my machine is set for 30c. I wouldn't mind setting it for 15c. The actual coin mech, not the rejector, has metal bars for pathways. I am assuming if you move them to different positions, it would alter the price.
Usually, the manuals are just part descriptions, and a breakdown. Hopefully, there would be some information in it.
