Intertwinded >>SuS<< - Sauer Process mark
Eagle over M - Preliminary proof of black powder for scatterguns or multi-barreled longarms.
Eagle over N coupled w/ Oak Leaf - Definitive Proof w/ Nitro Powder for scatterguns & multi-barreled longarms
Not sure on the single Eagle over N on the 16 bore, maybe the left the Oak Leaf off or one Oak Leaf does it all???
Those on the water-table I believe to be coupled.
16/70 - Bore diameter & chamber depth
7X57R - Calibre
12 54 - Month & Year of proof
