We had a pic of one in a recent thread; I thought I'd show mine, which has a couple of nice features. Here's the tin; far from pristine, but decent: Many of this model have a plain, unincised tank with a sticker. This is one of the ones with the very nice incised fount: You can see in that photo and the next two something I haven't seen on any other brass stove- a copper spirit cup. The photos show it, but not with quite the contrast as in person: I am very fond of the one-pint "21s". I've always assumed they took it from the Primus 210-- Radius 21, Burmos 21, Svea 121....
