This is a superb, untouched, unmarked Deringer.  The barrel is 4 inches in length and the overall length is 8 1/2 inches.   The barrel and lock have a very light rust with the barrel showing a majority of the original finish.  The wood retains almost all of the original finish.  There are no significant dents, dings, etc.  The ramrod is slotted iron with a brass tip and is original.  The gun is mechanically perfect and has really sharp checkering.  I don't know who made this little gun.  There are no markings and no proof marks on the bottom of the barrel.  I assume it is American made but I don't know where.   A very pleasant little gun.  SOLD!!
