Sorry I can't give you a solid lead Frank, but I CAN say that I ordered a couple of K&M's brass cases and they're the bees knees. The lead time was nuts, but I wasn't in a hurry, and am glad to have a pair of heirloom grade cases. I also spent an enjoyable hour visiting with the company owner.

IF you need an aluminum case, I'd consider this one;

I subscribe to the philosophy of multiple fire starting means, and that includes storm proof matches. All of mine ride inside UCO plastic cases, which ultimately might not be as impact resistant as an aluminum case, but hold a LOT more matches-------------if I'm down to those because my other matches, lighters, and ferrocerium rods have failed. I'm much more concerned about an unforeseen serious injury than being without fire, given the gear I carry.
Just my .02c.

Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery.
