What is the earliest / oldest known 809 cosmonaute serial number ?

[Dracha]

I was browsing the forum looking at all the very nice 1962 pictures and info and am wondering if anyone has been able to narrow down what the earliest (oldest) Cosmonaute is ?

warning! , assumptions made in the below !
==========================================

the below serial number info is taken from http://www.navitimer.net

looking at the serial number list for 1962 , which runs from
947804 (to) 963553, there have been 15750 chronograph's made. I think we can safely assume that the majority where 12hr version Navitimers.

And since the Aurora 7 took off on may 24th (the 146th day of the year, approx 1/3rd into the year = 1/3rd into the serial number list ?)

Can we assume that the first 'true' 809 cosmonaute , has to have had a serial number at least starting with (1/3rd into the serial number list) 947804+5250 = 953054 ?

Or were 24hr 809 Cosmonautes already 'readily' available before the aurora 7 mission, which would mean this whole hypothesis goes out the window :-)

does anyone have an idea how many (approx) 809's were made in 1962 ?

thanks for reading my sunday morning thoughts :-)

I own a Cosmonaute that starts with 955xxx, but I recall that we had a discussion a while back about another Cosmonaute which also started with 95xxxx. So that might give us a starting point.
