Hi Raimey,

thank you very much for bringing this to our attention! Most interesting! Firstly, because it shows, Sauer delivered in the white barrels to Belgian gun makers (I didnt know that), secondly, yes, regarding the date strings this could be a Rosettas stone, because I also noticed on some pre-1912 barrels some codes similar to the Austrian style date codes. Dont have a photo at hand right now, but I have seen such date strings also.

Regards

Martin
