Another Sauer with unique 4 number kalibre being >>1681<< and >>1710<< along with the letters >>SE<< all which were applied by Liége mechanics and the reset of that German Chicken Scratching are Sauer internal Process marks including the Large & Small Crowns.
Skimmin' thru several threads, I see:
S Band
S Bern
D Bern
SE - which I think to be S. Étoile....
RDAM....
Typically one sees rough tube diameters applied by Liége mechanics but this specific Sauer has 4 digits.
Hause & I have been discussing such, but since the numbers are sometimes so close, like 181, 182, I hold that the number is for each individual tube, but again I do not know what the reason was for 4 numbers???
