The repainting of all the R-10's with the aqua blue & white with stripe occurred sometime slowly starting December 1965 and ending in June 1967. Everyone knows that car #3331 was the first unit to be completed, and was used in much of NYC Transit's publicity photographs.
But then, the R-10's was going through some subtle cosmetic changes and attention like never before. All fiberglass hard seats were being installed on the fleet between July 1967 and February 1968, and the cars went through the repainting process with the white stripe filled in between August 1968 and March 1969.
Car #3189 had those additional seats installed sometime during the spring of 1969. Finally, the R-10's went back to the paint shop again for the MTA silver/blue combo scheme between August 1969 and June 1972.
Finally, through some research from some past E.R.A. New York Division "Bulletins" from 1964, and combined with what's in my slide collection, there were actually NINE red R-10's painted. They were cars #1822 (ren-2969), #1825 (ren-2972), #1850 (ren-2997), #3099, #3101, #3137, #3234, #3334 and #3342.
