On rare occaisions I've seen one on ebay.
You could check with Joe St. Charles.
[email protected]he seems to have some of the old Bear parts around. You wouldn't have to have these milled. They are not that diffcult of a shape to deal with. I would think that with a coping saw, small drill, files and sandpaper a guy could probably do a pretty nice job at creating a replacement. Many shops that make sports trophies can do laser burning in wood or plastic.
