There have been many extremely rare and correct machines sold at VCA over the years, I know because I have bought some and lots of junkers. The problem is being able to tell the difference between the good ones and the ones that are made up or being dumped. In the case of the Wonder Clock. Records have survived that date and tell where they were sold by serial numbers. That is an original machine. I neither own or will profit from its sale. I think rather than raise eyebrows on a specific machine we are unsure about, it's better to just say, every machine you are interested in should be checked out by you or someone knowledgable about it.
