Hi Skeeves, your spiritstove is a Hasag No.29 Your Model seems to be built between 1928 and 1940. Is's price was 3,25 german Reichsmark and it was supposed to boil up 1 Ltr. of water in 6 minutes. I have the same model, it is very reliable. Best regards, Björn
Yep, earlier models had a tankscrew with the old brandlabel (Gearwheel, torch and wings) I do have the same one in the older version. Best regards, Björn
