My brother saw this stove exhibited by Meadow Foundry at the Great Dorset Steam Fair and put me on to the website. Looks like it could be a useful stove in an emergency. And its British made in Devon.

good find, i like the simple design!
wildstoves do a similar thing, a bit more robust for a permanent camp or bol:

That looks a good size, Ive wanted a frontier stove for awhile, that's a decent price too . maybe one day
