A 1920's Merkel S x S 16 gauge, scalloped back A & D action, boxlock, 28" barrels choked .010 and .020, straight grip stock, completely and properly restored about 7 or 8 years ago. I only shoot upland, from South Georgia quail to Iowa pheasants, it's perfect for me and if I sold every gun in my vault this would be the last one standing. Second favorite would be an Ugartechea clone of a Merkel 303 in 20 gauge, a sidelock O/U somewhat tighter choked than the Merkel above, my favorite O/U gun that I have, more so than a couple of very nice Merkel O/U's. William Larkin Moore tells me they only made 6 of these guns in 20 gauge and have not made them now for 20 years or more.
