If you have a late 50's early 60's Williams Baseball game below you are probably aware that PBR ran out of stock of the spring a couple of years ago and they were not viable to have remade.
I eventually found a spring manufacturer able to make the spring for an acceptable price so I ordered 100 and will sell in pairs to all that needs them. I also had the spring made a little stronger (8-10%) as these games are not as pristine inside the pitch mechanism and they need to 'pop' that ball. I fitted one to my recent Short stop restore that has a can motor and it shoots the ball out now. I can't hit it every time.
I don't think that these springs will last long so even if you may not believe you need one today you need to invest as I won't need to make these ever again. So a pack of two is $15.00 + postage. I will sent a pack or two out next week and will find out the minimum postage and update.
