Mr. Ed(nhhe52). The FA1 and FB1 locomotives "...were delivered in [1947 in] the flashy warm orange livery with silver gray pin stripes and dark green side grilling and roof, and had through steam lines for use as trailing units behind steam generator-equipped locomotive in passenger service if necessary...In 1951 additonal "B" units numbered 465-469, class DER-2c, arrived...came in the green and gold livery...things started innocently enough with the red/white/black livery in 1956, simplified to red and black in 1958,..." From page 440 of Mr. J.W. Swanburg's New Haven Power 1838 - 1968 (1988). Interesting is unit 0403 as listed in Preliminary NHRTIA: 4.5.1 and 4.5.2 (1976). The chart shows photographic evidence that 0403 was painted in the Hunter Green Imitation Gold livery in July 1951 and the Hunter Green Warm Orange livery in November 1964. This is the only FA1 that was photographed in the Warm Orange with pin stripe livery after being recorded in a later livery. It also shows that the FB2 units were delivered in the Hunter Green Imitation Gold livery, and unit 469 was still in that livery in February 1967. I believe the FB2 paint listing is incorrect on the data sheet since the NHRHTA's New Haven Color Guide (1998) shows the locomotive colors for the period of 1948 to 1953 was Pullman Green NH Serial #13 and not the Hunter Green Imitation Gold livery shown on the data sheet, which was a preliminary data set.
So, the short answer is only FA1 0403 was repainted in the Warm Orange with pin stripe livery, and depending on the year it was repainted the green should be Pullman Green NH Serial #13 if painted in 1953, or 401 Green NH Serial #401 if painted between 1954 and 1955. Hope this helps.
