Looking for brain tanned moose hide

[Cruzatte]

Back when I was more active, some pieces of my kit wore out, and I've yet to replace them. I've been looking on the 'net for a ¼ brain tanned smoked moose hide as my old moccasins have been reduced to so much scrap leather. I've come up dry. Any suggestions would be appreciated. These folks are out of stock and don't know when, if ever they'll have any.
