Question re: early "C" black lenses

[David Winter]

When were black "C" lenses first available?

It seems that black "C" lenses were available about
the same time as T-Star arrived.

Can anyone offer a timeline for both black C lenses and
T-Star? Were all lenses available with T-Star and/or black
finish at the same time?

A straight time line is difficult as T* and black lenses came mixed.
But it appears that the T* came in about 1973 and black barrels in around 1975.
But wide lenses got the multi-coating early (1972 for 38/4,5 Biogon) and long tele lenses late (1976 for the 500/8 Tele-Tessar).

A study of Rick Nordin's Hasselblad Compendium book will help for sure.
