I have acquired a Blue Flame heater and am trying to find out what model it is. The frame has a twisted detail at the top if that helps? I also have an operating manual as we live near the UK supplier of Aladdin parts in Yorkshire.
Looks like a stock standard Series 15. They came in a few colours, quite often a green or crème. They are reasonably common and you can still get some parts. It should restore quite well.
