First year brass and blue Ruger Old Army, fairly rare, they did not put brass Super Blackhawk grip frames on very many of them. Modified cylinder can hold over 50g of FFFg...
Kind of partial to an equally rare Smith and Wesson 3rd Model .44 Hand Ejector, a.k.a., Model of 1926, a.k.a. Wolf and Klar. Factory full nickel plate including the grooved (target) hammer and trigger, with carved mother of pearl grip scales.
Jam-o-matics? Don't much care for them, but I do have a 1936 CZ24 in 9mm Browning/short (better known as .380). War trophy, came back from the European Theater in WW2. Father in law swapped an Arisaka submachine gun for it straight across.
Hmm, shotguns is a tough call, do I like the 1800s caplock 12g double, the 16g pump, or the 14" barreled .410 better... and yes, the A.O.W. is properly licensed...

Rifles is a serious tough choice, Stevens 44 Favorite in .22S/L, Marlin Glenfield M20 in .22S/L/LR, Canadian Centennial Winchester M6702 .30/30 (I actually hate this carbine), .50 T/C Hawken, .54 Lyman Great Plains... or the pre-64 M70 Winchester in .243 with a trigger pull measured in ounces.
