You just pictured a shoulder bag on your blog in a picture with a leatherman Wave. I was wondering what kind of bag, as the mussette bags I see dont have snaps. Thanks.
It's an English MKVII Gas Mask bag, made in the 1940's.
Kind of rare but something similar may be found in surplus stores. Just make sure the cotton canvas isn't rotten.
I use this bag when I'm not carrying that much stuff.
