Dating transistors?

I have a number of old RCA germaniums and they always have some sort of code on them, a combination of letters and numbers I can make no sense of. Was there some sort of date code they put on these? Anyone know how to read it?

This.
Though all women are also bipolar and need careful biasing.

And the difference between NPN and PNP ?

We digress - and get naughty, because we can - but to answer your question, lowbrow, do you have any of the codes ?
We may be able to fathom something from them if you could let us have the details.

I've just found an RCA transistor manual at http://ebookbrowse.com/rca-transistor-m ... d236908415 - which may be of use. It seems to only have transistors beginning with 2N . . . though.
Thinking back to my childhood (such a long time ago), there were AC... (such as AC127, AC128), OC... (such as OC71, OC44), and manufacturer-specific numbers such as Newmarket (NKT...)
I can't recall any numbers/codes that were RCA specific, though.
