Can You Identify Me?

Long story as short as possible. I was rooting around in my big storage box for some 15mm Dark Ages heavy cavalry and came across this guy and seven of his identical brothers:

No horses seem to be associated with them. I would like to get more, but I have no idea who makes or made them. The spear and the softness of the metal screams Essex, but the chainmail does not. Besides Essex, I've looked at Chariot Miniatures and Gladiator Miniatures and have come up empty. If not Essex, my money is on Chariot. It might be a discontinued line. If anyone happens to know, let me know.
