How do I tell when my Duo was manufactured

[Mavarick]

Hi all.
I recently picked up a second hand Duo,
I already have one, how can I tell which one would be the newer of the 2?
thanks

There may be a stamp on the motherboard with the revision number (not to be confused with the cloned receivers and their version numbers).

I had a V1.3 and a V2.4.

thanks very much, will check that out, they are both good ones, the one I just got has Pli on it and no hard drive , and after using Vix is not that easy even to navigate round,
