Thanks for the info. I have not seen them being used before 1947 yet, but I do not have many samples. Definitely I own one 1946 manufactured watch with a 380 movements in it whereas my earliest 385 is from 1948.
I have not checked very carefully (at least not from under the dial), what the differences between the 380 and the 385 are, they look very much the same(Jack, you mentioned the size is different?). Obvious difference is that all 380/81 movements seem to be gold plated whereas all the 385/386 I have are nickle plated.
So the switch may already have happened early 1946?
