I went to an antique shop a few days ago, and there it was among lots of other old things. It had to come home with me. It had obviously been exposed to moisture recently, because the boiler supports and the spanner had a lot of fresh rust. And the box is a little deformed. But after a good cleaning, the stove was as good as new. Flameshot Here it is waiting for me
Interesting! The box looks very much like the one supplied with the 106, but none of the catalogues mention the 121 in anything other than a tin. Beautiful stove, unexpected finds are always fun!
@Blackdog I have a 106L too. The box is apparently similar, but with a different surface. The box makes the stove a little more interesting
