I thought I had posted this last night but I don't see it so here goes again. Under barrels: Single Crown over PT on both tubes. so that should be ordinary proof.for smokeless, Murat Cizeron under left barrel as is Acier au Creuset. the sideways crown with crossed fronds and stars and Stetienne assembled proof mark on each barrel and also a G with what looks like an M made of what I think are arrows. Barrel flats under right tube are marked EPR.Supericure and Medaille D'OR. (Note that all letters are Capital letters). Water tables are marked with the single crown over PT and Murat plus serial number. Pins through action all screws are timed. Oak Leaves deeply engraved on top of faces and rest of metalwork engraved with a light, minimalist pattern. Pins, screws surrounded with a floral pattern with screw as center of flower. Top of action, including top lever and safety have highest concentration of engraving. Wood hand engraved but well worn. Another interesting note is action is cut to resemble sideplates. The gun's story as per my Dad. He was an MP during WWII and stayed over in Munich for the occupation. A German Farmer who's daughter worked in the offices got in contact with my Dad because she had told him that Dad loved guns. At that time guns were being rounded up and destroyed. Well, Dad met with the German family and the farmer dug the oilcloth gun out of a pile of mostly manure where it had been hidden from the Nazis. And so the old girl ended up migrating to the US. It's the gun that I used when I started hunting. I should add that barrels are a little shy of 27" and extractors only. IT was a short 16 but chambers were lengthened in the 60's.
