Takumars/Auto/Super came with either black on white or white on black.The few reports of any other colour come from post production homework.Probably yours too.
I have a 55mm f2.2 Zebra (with a black aperture ring, and blue feet-scale). Bought used with an Heiland H2...
The only Super Takumar lens that couldn't be used on the SV was the 50/1,4, as the rear could touch the mirror. A later version of the SV solved this problem.
Maybe I'm wrong. If so, please let me know, as I'm seeing some confusing info on various forums about this issue.
