These are the spanish militia, the other half of the Spanish Guerilla set from Hat Industries. There is enough on that set to come up with these 3 small units of militiamen.
There is rather scarce information on colors of napoleonic spanish militia uniforms on the web, but what little I could find suggests white, blue and brown were the main colors used, so I painted each unit in one of those.
With these, I finally finish that which was one of my first kits of napoleonics 1/72, bought a few years ago and left to sit on my shelves for a while before getting their well deserved turn on the painting qeue.
