This is a Nulite 2m lantern sold by the company Gerrit Janssen/ Summit in Arnhem Netherlands. This lantern is stamped "Summit lantern " and "Gerrit Janssen Arnhem (Holland)" on the legs of the metal frame inside the lantern. I've seen a lot Summit lanterns here in the Netherlands stamped with only "Summit " on the tank, or with a label with the name Summit and a model number. But I've never seen a Summit lantern with the name of the owner of the company, Gerrit Janssen.
@Johan Osinga You’ve restored it beautifully. I also have the same model. Mine has the manufacturer’s name stamped on the frame. Shinzo
