OK, if I understand this, then Swiss military contract 1900s, Test Lugers for the US Army, other 1900 American Eagles, etc. had their own ranges of serial numbers, as did the commercials. The number series/range for each type would be different, according to contract or category? There's documentation to date the other categories' ranges v. dates of production, but the straight commercials were built sporadically, and though consistent in their sequential numbering , there's no way to discern exactly when they might have been built? Other than to say that the serial number of mine is closer to the beginning than the 90-some thousand end in 1921, what would be a "reasonable " guess as to its birthday?

Was there a point in time when the 1900 commercials were replaced by the '06 design/configuration, or were 1900 style also produced until 1921? 1921 was the beginning of what we call "alphabet commercials"--with (up to)4-digit numbers with suffix, right?
Was the same serial number range of 1-90+k continued through all commercial variations up until 1921?
