Really cool vintage catalogue/resource guide that Krista Associates (orginal US importer of Jotul) put out in the 70s. Super detailed info on all the models they imported back then. Even the rare ones. All the testing graphs, info on who did the reliefs. And some very interesting tips and facts about woodstove safety. This is a 77 copy I got off ebay. Its about the closest thing ive found to a manual for my Lumberjack 380.
