I'm no expert at this period, but according to this page:
It says that according to the regulation of the m1802 uniform color sergants had 1 galoon in the hat.
According to the m1807 regulations ncos and musicisians should have a tricorn, the tricorn should have a silver galoon, a braid? and button.
Thanks a lot. I look for many months for these informations. This is my first contact with the site you sent me the link.
Hope you will find the answer to your question. I'll google myself for you - who knows, I might get lucky and provide you with an answer.
Re: Re: Origins of Prussian moustaches and powdered hair?
In 1806 the Prussians only wore wigs or powdered hair on church parade. During the reign of Frederick the Great the moustaches were stiffened. White wigs came into fashion in the early 30ies of the 18th century.
