Sell to another attendee; if it's in good shape, you'll get plenty of offers.
I had a funny moment at one show; I passed a table manned by some folks I'd watched in action at previous shows (and who had thereby earned my utter contempt for their behavior & outright deceptive statements). One of 'em asked, optimistically, "Whatcha got in the bag?" As it happened, I had a Colt Detective Special, excellent condition, in the backpack I carry to shows (I'm optimistic, too . . .
). I ordinarily wouldn't have even acknowledged his question (I have neither time nor patience for liars). However, as I had scanned his wares, I had noticed something, so I put on my most gullible smile, withdrew the Colt, and handed it over for his inspection.
He eagerly inspected, then asked, "How much?" I named what I considered a fair price. The dealer declared that it was a nice revolver, but the prices of Colts weren't as high as they had been, folks had inflated ideas of their worth, etc., etc., and countered with a much lower amount (big surprise!
).
I looked suitably confused, pointed to an identical Colt Detective Special on his table with a price tag NEARLY THREE TIMES his offer for mine, and innocently inquired, "What is the difference between this 'un and that 'un??"
Dealer looked confused, muttered something about "It's a different variation . . ." as I retrieved my old Colt, laughed (loudly, to my shame
) and strolled away. Later sold it for my price to another customer at the show.
