Hey Bro,
I still haven't been able to get a pic of mine on here. My camera is fukd and nobody else here has one good enough to where you can read the label. But mine are identical to these, which I believe are yours:

Mine have a number(635228) but no "Lot", shelf life is 3 years. My box looks like the one in this pic:

The only difference I see as far as the amps is the "Lot". The number at the bottom is also the same: 20043/109w. I am not positive but I believe I have read that the 3 #s after the / refer to the intended distributing country. Another thing you will notice if you got boxes: I am not a language major, but I think that is poorly written Italian on the amp and box. The instructions inside are in English, French, and I believe Dutch(maybe German). This may have no relevance but just something to think about. I am still doing some checking around. I will post if I come across anything useful.
Again, mine were purchased at a pharmacy in a rich neighborhood in Baghdad.
