It's a late model Ideal 55 basically. It was the last inception of the slider vendor by Ideal. it still used a mechanical coin mech/slug-rejector as the earlier models, and like those models , it doesn't still didn't give change either..
It's a similar style to the True & Beverage-air chest coolers of it's time. there were two loading door features ( depending which model it was) on one what appears to be the front of the machine is in fact the loading door, when you unlock the latch, the front hinges out so you can load the sodas into the rack. the other option was as the original series , and loaded through the side door. as I recall, these units were labeled as "made in Canada"
the compressor is a common 1/5 HP system, and is easy enough to service if need.
