Well, the firearm I currently own and treasure most is my Walther PPK/S. Yep, it's fairly new, and yep, I have several S&W and Colt revolvers, but my dad gave me the Walther as a gift. When he passes one day (hopefully not anytime soon - he survived a heart attack 12 years ago and still trucking at 65), my most treasured firearms list will go up to five - the PPK/S, and his Colt Diamondback, S&W Model 66 (no dash), Marlin Golden 39A, and Marlin 336.
