Collectable Gumball Machine

[street]

Did some checking on this gumball machine and looks to be very collectable who collects. I have two of them but no key. Would any know of a place on line I could do business with that may have item like this. I would like to be able to send a few pictures of key hole etc.. with some online company to find the right key. It sounds like most of the flat keys which this one takes opens most of these machines. I thought some of you may live close to a store or know of one that may handle or have items like this. I was hoping to find a collector etc.. that would know which key would fit instead of ordering many and not being sure.
Any help would be appreciated.
I like looking for old items but not considered a collector though. Thanks

Maybe something like this will fit. I just did a search on ebay for Vintage Gumball Machine Key. There are some loose keys too.
