From 1795 until 1807, the Model 1795 went through progressive changes.  By 1808, a pattern evolved which served as a model for the award of the 1808 contracts.  Some of the changes from the Model 1795 include: the hammer tip and frizzen tail are plain, the pan is rounded at the bottom and forged integral with the lock plate, with the exception of the date the marking is placed in front of the hammer, the stock is an inch shorter and the trigger guard is 2 inches shorter with the long, pointed finials changed to plain round ends.  This model was produced until 1815, when production of the Model 1812 began.    

     Our specimen is marked on the lock plate in front of the hammer in script “US” above an eagle and “SPRINGFIELD” below.  Behind the hammer is “1813”.  The trigger plate is marker “FCOY”.  The rear of the barrel is marked “P” eagle head “V”.  The top of the butt plate is marked “1810”.  A six-sided star is marked on the left side of the stock and a “D” is carved on the right side of the stock.  The bayonet is marked “US” “JL”.  The socket is marked “H” “d” “88” “5”.
