Well it turns out the combo lock on my hard-sided canvas/leather shotgun case just failed and I found a replacement online. This site that I found would also be a great source for all the buckles, rings, leather straps and other misc hardware needed for those shooting sticks -- everything you need, except for the wood and skills.

I'm posting this info here in this forum, so more of those who might be interested in making a set of those shooting sticks can see it.

Hope this helps someone.
