Armi San Marco produced this 1851 3rd Model Dragoon with an 18" Barrel.  It was marketed by both Navy Arms and EMF.  It originally came with a steel hardware shoulder stock and holster.  There were around 5000 produced.  The production of the steel hardware shoulder stocks ceased in around 1974-75 so the last sets were supplied with brass hardware shoulder stocks with the brass being blued.  Less than 500 came with the blued brass hardware.  This is the only blued brass shoulder stock for the Dragoon that I have ever observed in 20yrs of collecting.  The Dragoon stocks are very rare with both the brass or steel hardware.  The last steel hardware stock sold was in April, 2013, for $1000.  The Dragoon brass hardware stocks are in the $600+ range.
