all amps on this pic are real.
1) early version: brown amp
2) second version: red writing
3) current version: black writing
versions 1 and 2 were slightly less sterile, but the real thing nonetheless.
version 2 (red) was not destined for export out of Iran. But you might happen upon it.
Note that the early 'black' versions have exp date burned on the amp, as do the fakes. However you'll notice it says 'exp. :' instead of 'exp.'
Currently the exp date is imprinted (like the first pic in the post). There are no fakes of those (yet?).
