not sure if these components are of use to anyone but I needed a 2 coin slot and a 3 coin slot bezel for 90's games. These are up at Shapeways in plastic that can be painted.
For us Aussies and I am sure Europeans the 3 coin bezel has often screwed and hacked and when we want to shop out a game this part is near impossible to find - unless someone can locate a supplier.
The screw holes in the back of the bezels are self tapping using your own screws.
Note: this post originally stated what would be done but all the designing has been completed so now adjusted to show the final products. See images of the range or head to the link.
