We held "without seeing the light" in the family these guns.
The issue is that I have some information and the same no.
1 - legends are Waffenfabrik-Mauser Mauser-Werke and then.
I have understood that the name change was in 1922.
2-two guns (a similar one and one equals) with serial numbers # 22 and # 29.
One was Mr. Lucas Visser Hinderickus known collector in the Netherlands (recently died) and sold weapons. The other unknown to the owner.
Mine also have 2-digit serial numbers are continuous, but odd.
The issue is that no patents of these guns.
Only patented several pieces.
The theme is the year of construction? known or assumed! Most conincide in 1916.
Thanks for the info
PD are both 9 mm Parabellum (9 mm Luger = 9x19)
