Brunswick's hulans...i think...
Good masters.

Dear Marco,

Thanks for that suggestion. I did not consider Brunswick.

The information that I have has them with shoulder straps only and no fringes, a uniform based on Austrian uhlans, whether 1809 or Waterloo?

Certainly an easy conversion to represent them thus and, as you note, lovely masters!

Regards, James

I too am starting to think they may indeed be Austrian or Brunswick. Im not sure about the epaulette either but at least that can be removed with a scalpel/file. Really nice troopers anyway.

Dear Strelets,

Please could you tell us, which uhlans you have in mind when you put only one epaulette on one shoulder?

Thanks a lot in advance an have a nice weekend

Hmm.....possibly Minuteman. Although they still dont look quite right for those guys

Dunno, im still thinking Austrians but epaulette has got me confused. Ive seen late war Austrian Uhlans with it, but the bottom of the tunic on the masters is that of earlier in the war, when I think they didnt have epaulettes. Problem is different sources show different things. Especially watercolour artworks.
Are they something like the 2nd Prince Schwarzenberg Uhlans??

Guess we will find out eventually!
