Hi Zhang,
let's try to answer your question ...

As we know at least 4 types of particular camera are known nowadays.
First (earliest) version starts with #5924741 (seen on Mir manual guide). The first real camera belongs to Viktor Suglob with #5924765, the latest known so far belongs to Yuriy Davidenko #5928690.
1st type approximate range: #5924741-#5928800, quantity appr.
4000 units;
2nd type approximate range: #5928800-#5947000, quantity appr.
18500 units;
3rd type approximate range: #5947000-#5957000. I have to stop now, while this transitional version was mixed with 4th type cameras since #5949000. I can only guess about proportion between type-3 and type-4 cameras, but I think, that remains of old-type bodies couldn't exceed 40 per cents of total 10000 units amount. So quantity appr.
4000-4500 units for 3rd type.
4th version is the most common to find. I have calculated, that appr. 60000 cameras were released in 1959 and appr. 77000 in 1960, total amount apr.
135000 units. I'm not sure you'd like to see my calculation (just ask if interested), but my numbers are close enough to official KMZ database.
Is it enough to answer your question?

Any comments?
