antique lead soldiers

Some old soldier toys from my family collection.
1. the horses appear to have headless riders. The heads were likely broken off during war games. I find no markings on this tiny piece.
2. all three pieces.
3. this fellow may be a Crusader as his shield bares a cross. And second soldier (silver color) has unusual headgear.
I have strained my eyes trying to read the markings on the bottoms with no luck. But I would think someone on here might have info on these pieces. They are tiny. Largest is 2 1/2 x 2 1/2. Carriage is 1"x 1/2"
