Everyone's definition is different... when I think of safe queen, I think of a gun that's expensive, rare, in pristine condition, and one that might get shown off as a pretty piece but rarely (or never!) fired.
Given that definition, I don't own any.
However, I have a few in my safe that don't get much play... old, family heirlooms that I will forever keep dear to my heart, but they don't make it out to the range very often.
In handguns, I have only one safe queen-- Smith & Wesson pre-model 10. Roy Jinks tells me that it's the S&W Hand Ejector, M&P, model of 1905, Fourth Change, built and shipped in 1921 to Huntington, WV. This one is a .38 Special, 6-inch barrel and fixed sights, nickel plated. It does not have the original grips, but wears mother of pearl. These were on it when my Grandfather bought it used in 1923. Serial number is 357xxx for any S&W data junkie who might wish to give me any more anecdotal information on it.
Alas, I have no host to upload a picture. I hope to rectify that problem eventually!
