I have always loved the depiction of the Cazadores a Caballo in the Funken books of the 1970's. I have thus chosen to show the unit in their earlier Tarleton style helmets (properly part of the uniform of the 1802-1805 Dragoons!).
The standard is that of the Numancia Dragoons. Even though the Cazadores likely didn't carry standards in the field, mine had to! I chose this flag chiefly because I was too cheap to pay for shipping for just 2 more of the otherwise excellent Adolfo Ramos flags.
The flag above is taken from the excellent Little Wars site: http://littlewars.se/spanish/dragoons.html
