Quoted from Vintage-Pinball:As for Silver, unfortunately the rails aren't present. I guess, seeing as the cabinet has been repainted too, an arcade owner decided to modernise it to not look so old when next to a shiny new machine
Don't be so quick to judge that your woodrails are missing. I've had a few woodrails come through my hands that were converted to metal rail, clearly in an attempt to make them look newer like the early 60's games that were coming on market at the time.
In each instance the metal rails were an aftermarket update that was available at the time and were applied over the existing woodrails. In each instance I removed the nails holding the metal rails to the side of the cabinet to reveal the original rails, some in exceptional condition.
