I bought a very nice Ithaca ,Grade 2 ,Flues, 16ga, shotgun at a Pittsburgh gun show about 15 years ago, at a great price.. It was the only non military type gun on the dealers table. Security wouldn't let me out of the door without a dealer signed tag on it. I went back to the dealer and explained my situation , he did furnish the receipt but said
who would take a gun like that ?, you'd be better off with a bag of rocks.
