They are Warlord Games plastic figures and have been painted up as belonging to Gustavus' Yellow Regiment. I know these probably did not, in fact, look remotely yellow in real life, but I'm calling wargamer's license on this. The Yellow Regiment needs to be painted yellow.
This brings by painted figures for TYW to 5 stands - one of musketeers and four of pikemen. The idea is to have two small playable forces by next summer. To start with, I'm doing the Yellow Regiment for the Swedes and a Bavarian regiment for the Imperialists / Catholic League. A regiment in this collection will consist of a number of pike and musketeer units, with about 1 pike unit to two musketeer units for both sides.
