Thanks for looking anyway. It fits all Williams from around 1960 to around 1967, then they went to the same kind of bar they used on through the 90s with minor variations. Prior the these they were either woodrails or the futuristic cabinet with the famous beverage shelf on the front. On those your hands are on the siderails when you play.
This is one part that most owners of this vintage machine would probably like to have available. I would buy two right now and probably more as I find more of these machines. The early 60s were a great time for Williams and they made some great looking and great playing games.
If even just the end caps were re-produced, it would be a big improvement over what we have.
