I've just bought a really good value 20D and grip to supplement my 5D. Out of curiosity, I went Googling for a date code. There's a suggestion that it's printed black-on-black somewhere in the mirror box / lens throat.
I can't see it, neither in the 20D nor the 5D; neither in bright daylight nor under a tungsten spot. Is there, in fact, such a code?
