Hi Everyone, I recently acquired this large heater style oil lamp and wondered if anyone can assist with its manufacturer? It is a centre draft and is fitted with a 30’’’ chimney and the wick knob had what I think is describe as a stylised rose. There are no other marks or inscriptions on it to give any idea who made it. Is it German? Or English? Or other nationality? It burns very brightly and generates a considerable amount of heat. Any info/suggestions welcome please! Thanks very much. Bozley.
