I will need to check some notes, to see what I have on the question on when they went from Cal 11 to Cal 11-I and when they went from Cal 11-I to Cal 12. I beleive that both these transitions occured fairly rapidly, but of course, there may have been hundreds of older movements on the shelves and in the bins, even when they introduced the new movements.
I am curious who else has lugs with the Cal 11-I markings on the back or maybe the "I" on the movement?
