Identify this chess set with heavy painted metal pieces Could someone please help me identify this chess set?

I purchased this from a flea market because I love the look of it. It now sits in my game room so the paint won't wear off.  

I have looked all over each piece using a magnifying glass and cannot find anything that would resemble a Makers Mark or other identifying marks.  The pieces are fairly heavy and feel like they are made of some type of metal yet a magnet does not stick to them.  I have pictures of each of the pieces so I could enlarge them to see better but even doing that I cannot find anything to help me identify this set.  Each of the pieces has a felt covering on the base.  I thought about removing one to see if there is anything to help me but am afraid of causing unnecessary damage.

Please let me know if I can provide any other information - not that I have much more - or any additional photos I can provide in helping with this question.
Some of the colors are a bit different, but that could be age or the nature of being hand painted. Also, you don't say how tall it is. That said, it looks very similar to a Crusaders vs. Saracens set, which has 5 inch tall kings. It is made of "polystone", a material made from crushed stone and polyurethane which is supposed to be durable and provide a heavy feel.
