Herb I have no idea, in high school penguins was our call sign (from Monty Python) and I am sure I would give you $250 for your penguin gun, but I bet it is worth a bit more, (guessing only) but figure they go from $750 - $900 at a gun show, unless the markings make it worth more?

Also, RK, O Club for sure . [img]wink.gif[/img]

Herb,
From the postage stamp size area of the pistol that you posted, I could see two parts that had definitely been replaced. Judging from the area shown, I would estimate the value in the $500/600 range.
