I love the small window! The big window can give you sunburn out in these parts! The 1959 sales literature document I have refers to the large back window as a "Full View Rear Window" and indicates that it is a full-view wrap-around rear window that is available at an extra cost.
The document continues to describe “A custom cab that provides foam rubber seat cushions and back rests, bright metal control knobs and window moldings, armrest, sunshade and cigarette lighter”. It continues with "Both Custom and De Luxe cabs are strikingly and durably upholstered".
I believe many of the items that were standard on the Custom cab could also be ordered as options at an extra cost on the De Luxe cab such as the full-view rear window. In the document I have, it does not indicate that the full-view rear window came as a standard item on the Custom cab; in fact it clearly denotes it as an “extra cost item” as I mentioned above.
I hope that helps!
