I suck at posting pics, but here's what I've got...
Pirate-y:
-1660's doglock pistol
-1750's British Sea Service flintlock pistol
-standard Naval cutlass
-Brown Bess musket (what the Continental Marines carried, for the most part)
Modern:
-Winchester Model 1866 Yellowboy (.45cal)
-Colt Single Action Army (.45 cal)
-M1903 Springfield, dated 1918
-M1911 (circa 1917)
-M1 Garand (dated 1943)
-M14 (late 60's)

The last two are my constant companions at the PD, now that we've done away with the shotguns...
