Unfortunately the bases were too big for the rule set I use, Chassepot and Needlegun. So I was forced to soak and separate the figures from the bases, which went without any problems. Once the figures were cleaned of glue and flocking, I searched for any markings.
Here is a picture of one of the infantrymen showing the round base. There were no markings on bottom of the base but there was something engraved on the top.
So now I have a battalion of Willie German infantry. With a little judicious repainting, mainly the cuffs, they have become the 2nd Battalion, 1st Hessian Infantry Regiment, Lieb Garde, of the 49th Infantry Brigade, 25th Ducal Hessian Infantry Division, IX Corps. Their compatriot 1st Battalion is composed of vintage 1" Scruby figures. And being the Lieb Garde, it is only fitting that both battalions be composed of such vintage figures.
