Mantle type kerosene (paraffin) lamps
My late father had one, which was a real Godsend during the power outages to which most of the UK was prone during the 1970s (these being entirely due to 'industrial action' on the part of workers in some 'essential industries', rather than actual faults on the network). It put out plenty of light, and also a repectable amount of heat, which was a bonus during the Winter months, but could be a disadvantage in a hot climate when the power and hence A/C is out.
It was not difficult to light/start, I would only advise not to rush it, wait for the evaporator to thoroughly heat before pumping. Premature pressurisation is probably the biggest killer of mantles. I only saw my father change a mantle once, he then bought about three 'spares', which I inherited, along with the lantern, thirty years later.
They are certainly 'neat' and/or 'quirky', but are an amazingly efficient source of light and heat in an emergency. I was sufficiently impressed that I bought myself one (new, ex-military, made by the 'Aladdin' parent company, Messrs. Willis and Bates, under the description of 'Lanterns, Kerosene, High Pressure') as soon as I got a home of my own. That one is still in it's unopened box (complete with all required accessories and spares (got to love military issue!) ) on a shelf in the spare bedroom.
I can't say that I ever noticed any smell from the lantern, apart from the aroma of 'meths' and kerosene during the lighting process.... Once thoroughly warm, it was virtually odourless!
Since I now have two of them, I suppose I could always sell one, but doubt that I ever will... Their usefulness outweighs their resale value. I would fully recommend buying one, even though (here in the UK) kerosene/paraffin is difficult to obtain and VERY expensive now.
Hope this helps!
