So when was the TA 5 Pro Vis introduced? This is more than idle curiosty. I've been debating a period-correct crank for a couple of 60's frames, and thought the TA was to new, but this photo says otherwise.

Whether or not that is a triple, it would seem to place the current TA arm design as early as 1961. Anyone have definite information on when the Cyclotourist type arms were introduced?

It is indeed a TA Pro 5 Vis triple crankset. And it's hard to tell but the rear derailleur appears to be a Simplex.
