90mm f/2 Summicron-M III question

Here's a question of mine that I put in another group that I'd also like to ask the experts in this group:

According to the serial numbers list @

http://www.l-camera-forum.com/leica-...ummicron-M_III

Numbers 2813801–2814900 (Lens nos. 2814052 & 2814349 are 90 mm not 35mm as listed) were Summicron-M f= 3.5 cm 1:2 (black.1) made in 1977

My 90 Summicron III is number 2814630. What year was it made? Might there be more 90s made in that range? Any other info?

Others exist by sure ... and my 2814779 is an example : probably they aren't few and the real year of production is hard to guess : the date of 1977 precedes by several years the official intro and is well know that one cannot make the quick equivalence "number of 1977=made in 1977". Those items are interesting because had a detail that, de facto, is a design mistake : the hood, when retracted, covers the f/stop ring, which can't be operated... ;another typical detail is the s/n on side (a solution that was indeed used on other Canadian lenses of that era)

Anyway, I think that those first series Summicrons are more in the hundreds than in the dozens, but never read numbers in the usual books.
