By typing the serial number "2010XX", the weapon is dated 1916 !.
This model was
manufactured in +- 570,000 copies until 1945.

1916
Model
M1903 POCKET HAMMERLESS (.32 AUTOMATIC)
By checking the punch on the barrel, there is the acronym (E GB) or a use of the weapon for the Belgian government.
Next to the serial number, there is a diamond with the letter "A".
And then, I found this website:

It turns out that it is one of the 1,200 copies of the contract requested by the Belgian Government from Colt and sent on March 8, 1916 for WW1.
Finally, I realize
that collector is not only accumulated a multitude of weapons but the pleasure
of
looking for his past, his career, his history, his identity!
