The book The New Haven Railroad's Streamline Passenger Fleet 1934 - 1953 by Goeffrey Doughty says on page 113 that "not all of the New Haven's stainless steel sleepers carried a green or orange band through the window portion of the car." On the same page there is a really bad photo in color of the sleeper Lookout Point. This sleeper was transferred to PC ownership in 1969. The photos shows a green Penn Central name board and what may be a green window band. On page 220 the book says "Penn Central renumbered the survivors into the 2200-series and some were even painted "deep water green," lettered in white with two intersecting "PC" letters where once the New Haven heralds had been. Many of the postwar stainless steel cars were renumbered into the 2500-series, receiving similar treatment with a green stripe where the McGinnis red-orange had been in the window section of the car."
I know this doesn't answer your question. However, some the cars that did survive to PC did get green window bands. More research is needed. NH Joe
