A woodcock in Europe is bigger and stouter than the version we have, here. A 12, with turn-of-the-century ammunition and a longer barrel wouldn’t seem too out of place, especially if the owner might toss a few decoys out on a pond or creek for ducks when he wasn’t hunting becasse.
Neat gun. Agree, would have been nice to see the rifling. When I was in France, I tagged along to a shop where that was done, and couldn’t help but notice that the lathe jigged up to cut rifling in shotgun barrels was an ancient US made Cincinnati-it was in use that day. Going from memory, the rifling was a three or four inch section, just past the 9” mark on the tubes. The barrels I saw were just getting one side rifled, the other side would have been conventionally choked.
Best,
