Perhaps even prettier than the Darne is the Manufrance Ideal (say "ee- day--ahl", not "eyedeel"). Round- actioned like the Scottish Dixons and McNaughtons which cost ten times more (though mechanically, because of their coil springs, more like the early side- lever Grants), light, strong, elegant, and ergonomic, they have some of the best lines nd handling characteristics in the world. They are sadly unappreciated here. When, a while ago, I was forced to sell a more expensive gun, I managed to get one "on the side" and still have money to pay bills, with the help of Kirby Hoyt at Vintage Doubles (a dealer whom I recommend without reservation).
It is a 16, the "ideal" ("eyedeel") gauge. See the clean lines?
It opens by squeezing an underlever-- extremely smooth and ergonomic.
And, being French, it has one innovation nobody else would think of: a sling that reels up and disappears into the stock.
