I Think...
...We've had this discussion before. If I recall correctly, the GE range with the brushed chrome on the little door was not the Stratoliner, but another model just below it. It wasn't quite as deluxe as the Stratoliner; the chrome panel was supposed to make that up to you. I think another airliner name was used for this model, but I cannot recall what it was; I've Googled Stratocruiser and Constellation to no avail.
Does anyone remember for sure?
