Answers by Expert:
I am able to answer questions on old coin operated machines. These include vending machines such as gumball or peanut or other machines such as trade stimulators that did not dispense a product but were positioned on a store's counter to bring in customers or stimulate trade. I specialize in machines by Pulver, Zeno, and Mansfield and also any old cast iron or wood machines.
I have been collecting these type of machines for about 10 years and have traveled the country to antique shows and auctions.

I have learned about many of these machines from traveling to view the collections of others.
