Well, keep us posted on the windows and if turning them around does the trick then this will be a real plus. Not sure why they had to reinvent the wheel on this model and go with a two piece system instead of the one piece window as used on the better HO models and like Lionel.
I'm also still smoldering about the "B" units that have different end profiles; one flat and one peaked. Flat is wrong, as no F-3 or F-7 "B" units used this profile. Changing it would not be worth the effort IMHO as the paint would be destroyed in the process, so we have to live with it.
My dynamic brake roof panel, although nicely painted with second and third colors lining up perfectly it's several shades different than the body color. I'll weather it, so not hard to fix.
There seemed to be a lot of QC issues with this model, including the nose grabs on the SF units, a cab interior that doesn't match any "F" units I can find photos of and other less important mistakes. Regardless of price or "price range" of this model, you expect it top be correct when you pay $600 for a single plastic engine.
""""No other manufacturer in its range produces glazes with such transparency and flatness.""""
That works two ways. On thin brass models this works perfectly. With a thick plastic body, applying flat glazing to the inside of the shell leave a cab thickness of 6"+ . My Lionel shells have wonderful windows in my opinion and they protrude into the opening so you don't have the large amount of body thickness to deal with. I guess a personal choice.
