I recently photographed a Canon de 75 Md. 1897 here in Romania.
Unfortunatly the gun is a wreck, guarding a WW2 cemetery in Miraslau, Alba county, but there is a text visible on top of the barrel, just above the breech
n25677
ABS_1918
I assume the first is the individual serial of the gun, what is the second? Manufacturing date?
What else can be found out from the serial?
A number of these guns served from 1916 to 1945 with the Romanian Army.
