I know what all this stuff is and I can get all of it too. The Esso can is the toughest to find out of what you listed. I'm the only one I know of that's ever found any, so anyone that has one bought it from me.

The Indian-head can isn't too tough to find. I know where one is right now but the guy won't sell it. For the right amount I might be able to persuade him.

I'm doing a run of "Bobby Flasks" now with leather covers, but most of them are sold. I might have a few left. I also just got a Dean's cooler in. It's kind of sold. The "5th Winchester" guy has said he wants it but hasn't paid yet. I just sold a oriental tobacco tin on Friday.

Let me know what you are looking for and I can track it down in time.
I know you were asking about the Baikal shotgun, I have the model numbers for both the versions that are used on the show. I'm a little reluctant to give this info out "yet" because it was so hard to figure this out and I wanted to sell a couple first. I will spill the beans to the right people though.
BTW the Muela knife BW-22C isn't as much as it seems. The website in South America has it listed in their own currency. In US dollars it's around 300 bucks.
