In the very early years of my collecting a YZ chewing gum machine appeared in the window of a small antique shop just around the corner from where I lived. The shop was closed for the Christmas holidays and tantalisingly I waited every day for it to reopen. After a couple of weeks they reopened and I went to the shop to buy it and was most disappointed to find that it had been sold to a buyer in Perth, West Australia, a collector of vitreous enamel signs. So it’s probably still out there somewhere for Gameswat to find.
I also had another ACE chewing gum machine. It had been stored outside and although the vitreous enamel cover of the machine was in good condition, the mechanism inside was rusted and corroded.
