I've known that Sam collected serial numbers for a long time. So when I saw him at one of the Pacific Pinball Expos in Marin county hunched over a game and writing in his notebook I asked him what he was up to. He told me that he was documenting the colors and positions of the plastic playfield posts. He said that the post colors hadn't been documented so he was trying to capture that. I wonder how far along he is with that project.

For those who don't know many older EMs have playfield posts of several different colors.
