All three of those games should have the same profile of the wood rail. So yes you can use one for a model for the other 2.

As for the one that is painted, I would use a chemical paint stripper and take the paint off. I did that on a 1959 Gottlieb and found that the paint had been put on very early before the wood took on the darker oxidized look. I ended up with brand new looking wood rails without sanding them down.
Worse case is that you would need to sand them down but then you will have rails that look like new ones anyway, so why buy new ones?

In the US we do not recommend sanding the paint off due to lead.

If the new or sanded down rails look too new for you then use a stain to age them.

Good luck.
