Yes, there were larger models. I am betting the largest ones went down with the store buildings that had them. I was told that the larger DR monitor tops, open coils, didn't survive that well. Many of the larger cabinets had newer refrigeration systems installed once the original failed. I suspect many went to WWII scrap drives.
I certainly didn't need this, but they're rare. This is the only one I have seen in my twenty years or watching. I recently got a GE product manual from 1930. I'll try and post some of the pictures. It's only their refrigerator division.
