Contax serial numbers

[theendofthelaw]

Hello, I'm a contarex and alpa user. Recently I got a contax s2 which I'm going to use intensively. As a camera collector I always wonder how serial numbers of a specific brand works. Can someone help me decripting contax serial numbers. I'm also intersted in information about overal contax production. I found something but I'm still missing info about global production of contax model (RTS II, III, ST, RX, AX and S2/S2b). Any info helping me in depicting the numbers of contax procution is the welcome! Thanks

Hello,
as I received not answer to my previous request I will add some considerations based on a serial numers observation from ebay. This in the hope that readers looking to their own cameras can help me in further understanding Contax serial numbers. Assunptions are the following:
1. ST, RX, RTS III, S2, AX could share the same serial number sequence;
2. G1/G2 follow a different serial numbering system (Some G1 number would otherwise backdate cameras to 1992 which cannot be)
3. N1 and NX follow an own serial numbering system.

I also observed:
ST and RTS III share numbers up to >65XX
RTS III are more common up to 85XX
RX can be found up to 10.0XX
S2 60th ed (1992) start colose to 11.0XX
RX also share with AX number over 15.0XX up to 30.0XX (millennium ed. from 2000)

I hope that someone can help me determining the global production of the series ST, RX, RTS III, S2 and AX which seems to <40.000 pieces.
