How's this for a of a clash of eras? German cavalry lancer from WWI. Steel helmet like in WWII (for the first year of WWI soldiers wore cloth caps, can you believe it) gas mask, steel lance (with little eyelets for attaching a pennant!) and of course, the horse. Listening to Dan Carlin's Hardcore History "Blueprint for Armageddon" about WWI led me to this image.
