Did you notice he also has reproduction glass. Actually that was one of the reasons I stopped collecting pinball machines. They started to reproduce all the plastics and back glasses.
I have a wood rail pinball machine from the early 1950's. I pulled it out of the basement of an old luncheonette. I paid 100 dollars for it and I was once offered a 1000 dollars just for the glass. Today that glass is reproduced.
