The King's Germans
No one makes a bearskin drummer for the KGL which Mike Chappell's The King's German Legion (1) 1803-1812 (Osprey Men-At-Arms 338) tells me they had. I cut the shako off with wire cutters, filed the figure off to a point above the peak and sculpted the bearskin using Miliput or Greenstuff. By the way, it was some time before I saw what they looked like from the back and the cap should show the white horse of Hanover on a red field - which mine now do.
I have my skirmishers for each battalion represented proportionally. The rules I use (Grand Manner) provide for skirmish units of 6 figures which is a problem for me - my skirmishers being swept aside easily unless amalgamated for the brigade into one unit. I advise anyone wishing to represent their armies according to historical returns to make an exception with your skirmishers if figure numbers are important for game mechanics.
