Quote from the book:
QUANTITY MADE
3,500 to 4,000 in 9mm Parabellum
SERIAL NUMBER RANGE: 25050 to 69000.

Some combination of this set of marks was
used on commercial Luger production starting
in 1900 and proceeding through the 1906
pattern guns. The crown/B and crown/U
indicated the actual proof, while the crown/G
is thought to indicate a rifled barrel. Later
the crown/G was dropped, with the other two
marks being applied sideways

Also here (lugerforum.com) there is a proof mark page with the same info about BUG and BU. That's why I thought it should be one of the early productions.

P.S.:
With all respect I am not arguing, I am trying to understand As I am getting obsessed with Lugers now and reading about each proof mark - so interesting!
