The simple fact is all guns in 20, and more so in 28, bring a premium. I don't get it, but, that is the way it is, Darnes included. A Darne in 16 is about perfect. My preference to engraving on a Darne, or, an Ideal, is Rosace, bolder than English rose and scroll. English engraving looks good on the flat sides of an English boxlock or sidelock, those rounded areas need deeper engraving to make them look oh so graceful.
Since my suspicions are now confirmed about this gun, it is NOT a Stoeger import, it was imported as a used gun from England, of all places, if I am not mistaken. I'm not the only person who thinks an R is a better gun than a V, either.
Best,
Ted
