I think that stove started out as the Gerry stove made for/by Gerry Cunningham and sold with the Gerry branding. That was a high-end brand in the '60's and '70's.

I used to keep one in my mountain rescue pack along with a GI canteen cup. Nice little stoves and light. Thanks for the happy flashback Jim!
