I have two Columbus model 14's...I would like to trade the vending wheel parts to make one of mine a model 17 or a model 18 or purchase the parts I need to convert one of mine...The best I can tell, the only difference is in the vending wheel..If you have a vending wheel for a Columbus model 17 or 18 and want to swap or sell, please contact me. Thanks, Steve
