Bob, interesting that you mention the windshield contours. E units and F units had different windshields... The Fs are taller and steeper in angle...
Santiago, I have been thinking about this, trying to figure out what gave you that idea. Perhaps it was the 1949 production change in the mounting rubber?
Actually, prototype E and F units had identical windshields from 1937 until the end of production. There was a different method of mounting the glass, which -- on E-units -- started with the first E8, in August, 1949, and -- on F-units -- also changed in mid-1949, early in production of the F7. The "old" mounting used internal rubber gaskets inside the window frame, while the later version had an external grommet-style rubber mount and it looks bigger. the appearance on both the inside and the outside changed with the addition of the larger rubber mount. But, the glass was actually the same size and shape on all EMD streamlined cab units.
