I bought a couple of aftermarket cabs for my U25C: I had a 4-window version and the new ones are 2 window. Before I drill, score and file my way to 4 windows, anybody know offhand what RRs used U-boats with the two window arrangement? A cursory look on railpix and rrpicture archives didn’t yield much except for some Family Systems units that looked like plates had been bolted over the fore and aft of what had originally been 4-window units.
Thanks-
Mike
