I bought this machine many years ago because I thought the witness window feature was unusual. When it arrived, I noticed that it had a decal that was specific to the witness window variation. Little did I know that a picker friend would call me a few years later and sell me (sight unseen) a gum machine marquee he had picked up in Wisconsin. It turned out to be the specific marquee for this machine...a match that must have been arranged in heaven. This very machine is pictured on page 27 of Silent Salesmen Too. As far as I know, it is the only example of the complete machine with the correct marquee.
