This Deringer is what is referred to as a "Clark Clark."  It was manufactured by F. H. Clark, Memphis, Tennessee.  There are many Henry Deringers that are agent marked by F. H. Clark, but this is a different story.  A close reading of Doug Eberhart's book The Deringer in America will reveal that this gun turns up in three distinct variations.  Some have F. H. Clark, Memphis stamped on the breech.  Some have no markings at all and some have agent markings, i.e.. H. E. Dimick, St. Louis.  All three variations are clearly made by the same hands and all three will have an R C inspection stamp on the bottom of the barrel.  This is the unmarked variation of the F. H. Clark Southern Deringer.  The barrel is four inches in length and in about .45 caliber.  The overall length of the gun is about 8 1/2 inches.  It has a very smooth, even patination with slight wear, no repairs and no replacements.  A very pleasant looking Southern Deringer.  Price $3,750.
