Mr. Ed. I enlarged the picture and counted five letters in the first word of the name and four letters in the second word of the name. I then looked through NHRTI - 5.105 to 5.112 List No. 1 - Numerical Series Roster - 1971-1964 Standing Data and NHRHTA - 5.115 to 5.141 List No. 2 - New York, New Haven & Hartford R.R. Parlor, Sleeper & Dining Cars Standing Data. All the cars that had names with that letter combination were off the roster by 1930 on NHRTI - 5.105 to 5.112 List No. 1 - Numerical Series Roster - 1971-1964 Standing Data. In the NHRHTA - 5.115 to 5.141 List No. 2 - New York, New Haven & Hartford R.R. Parlor, Sleeper & Dining Cars Standing Data, only NH #2065, Woods Hole, Pullman Plan 3916, Lot 6077 on page 5.130, NH #750, Night Cove, Pullman Plan 3980, Lot 6304 and NH #755, Night Land, Pullman Plan 3980, Lot 6158 on page 5.133. The window configuration of the Night series sleepers on the air conditioning duct side does not match that in the picture, see page 528 in Mr. J. W. Swanberg's New Haven Power 1838 - 1968 (1988). Since the Woods Hole became an 88 seat Coach 612 in August 1949, I looked up Mr. Wayne Drummond's "Butterflies to Caterpillars" article in Shoreliner, vol. 21, iss. 3. I couldn't find a picture of the Woods Hole in the article, nor the window configuration of men's sloon, eight double windows, and woman's saloon of any of the Pullman Plan 3916 parlor cars.
So, my conclusion without photo evidence to support it, is the right hand side car lettered for the New Haven was the parlor car NH #2065 Woods Hole prior to its August 1949 conversion to Coach #612. This falls within the timeframe that DER-2a 0418 operating in the Warm Orange delivery scheme that started in 1947.
I'm clueless on the Pullman car.
