Hi Mike,
I just stumbled across this thread. My Dad, Rod Cannon, created the Craw-Walker and was the founder owner of Feature Lures. This was back in the eighties.
I happen to have a small stash of these, and some in the original packaging. But sadly I don't know if the molds are still available. The company was sold to Howard's tackle and they did not pursue to continue making or selling these.
It's fun to see this post! I'll try to attach a picture later...
Cheers Brady
