Swedish troops in Germany 1807- Help needed!

[traveller]

I am planning forces for the Swedish "Great sortie" from Stralsund April 1, 1807. The Swedish National Regiments are rather stright forward but I have not found suitable figures for the Rügen/Stralsund Landwehr (not sure this image is a perfect representation as they were described having some sort of Litewka and a top hat with black crest and white plume):



and the Swedish(recruited Germans) Engelbrecht Regiment


Engelbrecht Officer



I considered using Perry Napoleonic 1806 Saxons for the Engelbrecht Reg but I am not sure it is the best representation...

Grateful for any help!
