This is a very rare 80 bore (.36 caliber) Tranter Revolver which is serial number 12302.  It is marked, on top of the barrel "W. Tranter's Patent, Hyde & Goodrich, Agents for the United States South."  It was manufactured about 1860 and marketed by Hyde & Goodrich, New Orleans.  The gun is complete and functioning.  It has good checkering on the grips and a light patina over a relatively smooth surface.  It is cased in an American mahogany casing.  The case shows wear but appears to be an authentic period casing for this gun.  It has a correct Tranter's Patent 80 bore bullet mold., a Hawksley bag flask, an Eley cap tin and a period oiler.  Even the bullets in the case are old.  A very rare Southern import revolver.  SOLD!!
