This is an attic condition, straight out of the woods Confederate Enfield, bought by Sinclair, Hamilton & Company under contract with Confederate Ordnance.  Sinclair, Hamilton & Company had a large contract with the Confederate Government and purchased P-53 Enfields from many different makers.  Early in the war, Barnett had an individual contract to supply the Confederacy.  That contract was terminated and later his products seemed to be absorbed by the Sinclair Hamilton & Company purchases.  This gun has the Sinclair Hamilton & Company inspector mark "IC" stamped twice, opposite the lock in the stock.  One stamp is block letters and the second stamp is within a cartouche.  It is barely visible but the Sinclair Hamilton & Company mark (S over HC over an Arrow) is stamped on top of the butt stock, just in front of the butt plate tang.  The gun is missing its rear sight, front barrel band and ramrod.  There is a sliver of wood broken out at the nose cap on the left side.  The hammer will not cock, probably a broken sear spring.  I don't see any distinct rifling in the bore, there may be traces.  An attic, straight out of the woods, Confederate P-53 Enfield at a reasonable price.  Sold!!
