I bought this machine off CraigsList. Always wanted a pop machine in my basement.

I works, technically, but I think the coin mech was from another machine and not compatible with this machine. I swapped it out for another broken vending machine I had.
So this machine works, the pop gets COLD (almost too cold and I can't find the thermostat control).

Can anyone tell me what kind of machine i've purchased? I' have to buy a new locking bar and would like to set it up for free vend, but I need to figure out what kind of machine I have first.

Thanks.

I've got an old Pepsi vending machine. Its been sitting in my garage and now basement for 10 yrs and I finally found a replacement key from a local locksmith.

Here's a pic of the outside of the unit --> http://imageshack.us.../dscf1059m.jpg/


The unit was stored with cans in it for the last decade + and some of them appear to have leaked into the inside of the unit (its really a mess in there).
When I plug the unit it, The coils on the bottom get covered with ice, but the box never really cools.

so my questions are:
1) is this box worth fixing?
2) How do I fix the cooling problem? If I need a technician, who can repair this? The box isn't terrible light, and I wouldn't want to move it unless I had to.
3) Any recommendations for cleaning out the bottom of the box where it appears to be caked with dirt and pop residue.
