What Are These? - Figure ID

A friend at work gave these to me the other day. She has no idea where they came from. I'm guessing the armored warriors are pawns from a chess set. I'm not sure about the knights. They are definitely 15mm but I don't recognize the company or the sculptor. There are no marks on the bottom of the "pawns" the bottom of the bases for the knights have been filed down. They are all made of metal but they are not lead or pewter they are much harder than that. One of the knight's lances was bent and I had to exert force to get it back into position. If anyone out there has a clue about them let me know!
