BGresto probably a good first start for glass if they have that file or rough sample can be provided for the Backglass. Plastics are hard to come by for this age. I have a WMS fairway I had to scan in damaged plastics touch them up digitally and print them on translite material.

Don’t be too afraid to play your game. Things break and we are here to fix them.

On the cabinet paint, it depends on what paint they used. If latex house type paint which is the norm. Then if often can be removed. If rattle can paint, not so sure.

re latex: I removed blue paint from a 1950 Spot Bowler and while the original paint was rough it was still there. Used denatured alcohol, a plastic blade putty knife, and a plastic kitchen scrubby (not a 3M scratch pad), and over a weekend was able to get all the blue latex off.

re plastics: Yep, EJS is right, play it. I have probably played a couple hundred games on SB and haven't broken a plastic part yet.

There are some of us that can get translites made for those hard to find games.

Check these guys out...

Xylene also removes latex paint without removing paint underneath.
Available at home crapo or any hardware store.

Xylene should also work on rattle can paint.
