The local craigslist, Vancouver, BC, has a listing for a very old Kampkook two-burner. See:- http://vancouver.en.craigslist.ca/pml/clt/1921941244.html
What interested me about this old stove is the colour. I have a no4 that is getting its gob of green paint stripped off. The under colour is this same blue colour. I'm going to spray mine this colour when it's all cleaned up. I really like the perfect fancy cast iron grille. The stove works perfectly. Peter
