During the 'K's official existence from 1983(?)-88, you would find:
-R32s were largely on the 'G', 'N' and 'R' both before and after the great N/R switch of May '87. They also put in cameos on the 'B', 'D', 'L' and 'M'.
Interestingly, during that time, the 32s that ran out of Jamaica had their interiors redone so that the walls were beige and the inside doors were bright blue, a similar shade to what the outside doors originally were. If a 32 was just pulling in Queensbound at 5th Avenue or Lexington Avenue, you could immediately differentiate between an 'N' which was still covered in graffiti and had the orange inside doors, and an 'R', which was ungraffitied and had the blue doors. By summer 1987, all 32s were redone in this way. In summer 1988, the first overhauled 32s were on the 'R'.
The last R-32 I saw that was not given the 1988 overhaul was on the 'N' in May 1990.
The Mod 40s and 42s had a similar interior paint scheme during that time.
The 44s were almost exclusively on the 'A' during the eighties, still with the original 'bullseye' letter sign at the end, the long route strip map, the feeble door chime and the black-on-white car number plates. They pretty much left the Queens division after 1977 and the 'D' after 1980.
