Thank you for the compliments. The first set is a bag by Chris Crosby, a rifleman's knife by Dan DiStefano and the horn was made some 12 years ago by Austin Walker. The horn strap is by Travis Buare/Second Chance at History.
The second set is a bag by Travis/Second Chance, knife is made from an old file, forged into shape with a curly maple handle. I don't remember who made it but it wasn't by a bladesmith. The horn was made for me 7 years ago by someone whom I will decline to name as I do not like what made as compared to what I wanted along with what he charged me.
Anyway, both horns are airtight and function quite well. I've used them both although the Austin Walker has seen much more use.
I'll try and post a picture of my rifles later.
