an interesting question
VC few published the production of one type movement or reference . For example, the Chronometre Royal with caliber1007&1008.
In 1942, the VC produced Ref. 4240, triple calendar, using caliber 455 . Then caliber 485, 495 were produced, with models 4241, 4461, 4462, 4560 and 4623. During World War II, I thought the production was actually scarce. During the 1950s and 1960s, the average annual output was about 5000-6000.
the triple calendar vintage v&c made in 1942_1952? (mabe 1953) , how many about the total production of them? I guess it's less than 10% of the annual output, not more than 500 per year, maybe much less.
