I'm not so sure this is a Electric Junior... Even though there is a single lift lid, the cooler looks too wide to be a junior and has the cap catcher mounted on the front, not the right side; more over, no junior ever had a side access door.
I think this is one of the Atlas "Slider" Models, of which escapes me at the moment... Inside view picture shows something on the left inside wall that could have been where the shaft came through the cabinet for the gate...
Can you post a photo of the left side of this cooler?
In this case the dimensions would help as well.
