A lucky find! Perhaps you could take off the hood and remove the mica globe and photograph the burner system and also photograph the tank from various angles. Is the tank made from steel or brass and is the bottom of the tank made from steel or brass? So far no information has turned up on that firm, but the lantern may be a Hasag product which was made for a retailer. Perhaps some of our German members will have some information.
Neil McRae’s Pressure Lamp Catalogue has Sunlight Binning & Co. as a German company with little detail, and a photo of the sample label. He suggested that it is possibly Hasag. Could you please post detailed photos of your lantern in the Reference Gallery under Germany Other Brands. Best regards Tony
