The compressor is completely missing in this ebay box. It might have had a remote compressor, but it does not have anything now. It was not a sealed system, but rather had an external motor that had a belt that ran a big flywheel to evenly power the piston compressor. We picked up one like this at an estate sale. It was down in the basement, not running. As soon as we started to move it, it started leaking poisonous refrigerant. We opened the basement doors and got it outside as fast as possible and pulled it to a corner of the yard. Just before we left, John darted out of the van with something in his hand. He reached in and clipped the refrigerant line, which resulted in a cloud that rose through the trees and we headed for home to wash the awful smell off our bodies and out of our clothes. The next day we went back to pick up the box and the tree near it was covered in dead leaves. Jeff put a modern refrigeration system in it and put back the original mechanism for show. The construction is oak. The ice trays are tinned copper.
