I just received a BG Resto glass from Steve for Hokus Pokus. It is beautiful. Earlier in the summer did my own for Triple Action and not nearly as nice, but Steve didn't have TA artwork and I had no glass to send him. In the case of Hokus Pokus, I got the machine cheap enough, that still would make a couple of bucks if decided to sell it. So one of the decisions is whether the game is worth the cost of a good reproduction glass, or whether you don't care if you are upside down in the machine because you are going to keep it.
Oh, and Randy, lining up the score reels, credit window, and all the ball count and match numbers and lights was a real challenge on the TA backglass. We printed several full size white papers with just the numbers, and outlines for windows to put into the back box, then noted corrections, then did it again until everything matched correctly. Then cut the numbers and windows out of black sign vinyl and applied to the back side of the image to create the black out areas and numbers. Would do it again if needed, but not fun.
