I'm with you, skjos -- that "3" certainly doesn't appear to be the same as the other on the label, and has other appearance differences as well. There's a chance, of course, that it could have been done at the factory to denote a one-off in the series, but as you say, only a letter will ever confirm it.

Anyone checked the "TVA" prefix to see what it correlates with in other pistols?

It's a cool little pistol, for sure, but I tend toward a nicely-done and workmanlike modification of a longer production model using the 2213 or 2214 barrel. Just a guess, of course, and no disrespect intended to anyone.
