In the elder days of pinball. Pinball was just coming out of being a gambling machine and into its own.
The game play had some overlap with gambling but it had enough skill to keep it not gambling.
Woodrails were know for,
A. Non tradional itailan bottom.
B. Incentive to drain
C. Diffrent
Woodrail design did not have to conform to the norm.
Why not have a modern line of inspired woodrail designs. Capture the 1950s and 40s with vintage colors keep three inch flipers, wood legs, simple rules, no bonus, manual ball lift.
Keep it as a side option not made on the line.
