Miniature Portrait French Cavalry Officer Legion of Honor 1802

A superb hand painted miniature Portrait on Card of an officer in uniform of I believe a French Cavalry Officer with the Legion of Honor Medal of 1802. I think the uniform would date to the Napoleonic period of 1800 to 1820 but it is extremely difficult to make a more accurate date. The miniature portrait is painted on a thin card using pencil and watercolour and presented behind glass in a later carved wooden frame that dates to around 1900. The sitter is shown wearing a dark green tunic with red facing colour and black stock with gold buttons down the front and a medal with the legion of honor white cross and red ribbon. The size of the miniature is 140mm high x 104mm wide, the frame size is shown below.
