Hard to say how many pieces of the bolt assembly are missing with the bolt still in the rifle.
If all the bolt internals are missing, you're looking at over $80 in parts.
Complete bolt assemblies show up on eBay and other auction sites from time to time.
The Model X and Model 2X bolts will interchange. The later Lil' Champ bolt shows up all over the auction sites but is completely different and won't work on an X or 2X.

John, There's been confusion over who made these because of the Canadian patent, and some insist Cooey made them. I'm pretty certain that IJ made them, and the Canadian thing had to do with patent rights. Can you confirm that?

I've heard those rumors but can't confirm them myself.
I agree with you that the markings (that are only on some of the rifles BTW) was some sort of patent rights or possibly an export thing.
