I have 2 antique derringers for sale at one Price.  The first is a double .41 remington derringer that appears to function correctly.  The second is an engraved Favorite No. 1 marked derringer with ivory grips.  The hammer does not lock and the cylinder rotates freely - needs a little work but looks good.  One price of $1250 gets both.   Cash pick up only in Summerfield, NC. REDACTED for more information.  Thanks.
