Hello thank you for your comments regarding the rather confusing napoleonic figure.your guess about the possible identity of the unit it represents is right on track. I have been able to check my books and do some internet reserch about the cacadores. Hoewever about the unit of prussian reserve, the 3/21, not been able to check, can you please tell me your source for the 3/21 similarity or point me towards available references.
Regards
antonio
