What game is it for?.

There's a few design variations. Eg, up til around Hot Hand or Magic in 1979 they used the generic red white and blue design. If that is the one you are after, i think Retropin (Gavin) has made a decal, or made stencils for one in the past. Perhaps you could contact him and see what the go is.

Not easy to find a decent used one, as they suffer easy paint loss like the Gottlieb ones from the same era.

Good luck
