This gun's serial number is 21860, which places its production in 1863.  It has completely matching serial numbers, to include the barrel wedge.  It is mechanically excellent with strong markings and liberal amounts of finish, both case colors and blue, blending with a smooth patina.  The case colors on the frame, loading lever and hammer are particularly strong.  The grips retain 98% of the original varnish and there are significant amounts of silver plating left on the trigger guard and backstrap.  The safety pins, though somewhat worn, are still showing on the back of the cylinder.  It has a strong, clear barrel address and patent date in the flute of the cylinder.  It is 5 1/2 inches in barrel length and is in overall fine condition.  SOLD!!
