One, an Antonio Zoli 20 gauge I traded as partial payment to Griffin & Howe for a Belgian .405 double rifle. It sat forlornly on their rack for over a year, looking accusingly at me every time I walked into the Bernardsville store. I finally couldn't take the guilt any longer and bought it back for about 60% of the asking price.

I've still got it and, not counting the brief interregnum, have owned it almost 30 years.
