    G'day all,

    I thought some members might be interested in the results of some testing done on a variety of lamps in 1919. I do hope I'm not wearing out my welcome with the amount of posting I've been doing of late.

    The lantern used looks a bit like a San Diego. @Mackburner might know?

    The hollow wire set up looks interesting. I think that set up is to have a tank for fuel and a tank for air. The tanks that are usually found by todays collectors are fuel and air combined. I have seen three tanks used, fuel, air and water. I can see a logo on the tank but I can't make out what it is.

    The hollow wire lamp, hanging on the far right, nearly always referred to as a Gloria or Knight Light by todays collectors. Very often, they are neither.

    I found this photo after I had written the above.

    I do think the lantern to the far left is a San Diego, I think I have the patent to it. The majestic tall table lamp is a Pitner. If I had to guess what the wickie to the left is, I'd say a Rayo. The truth be known, I don't really have a clue about wickies. The lamp on the far right might be carbide - I dunno.

    I think the one second from the left is an early version of the Aladdin wick mantle lamp. That would match with 1919.

    Thanks Nils @Anthony may be able to confirm your guess.

    Nils, do you have an interest in wickies and carbide lamps too? I would think that with you living in Copenhagen you would come across that type of lamp and many differing varieties.

    What about hollow wire or gravity lamps? I suspect you would see your share of them?

    @Mackburner That is why you are the best in the business.

    I pinched this from Terry Marsh's site, If that is a sin, I'm sure the mods will delete it.

    This is a San Diego. I have two patents for the San Diego, one with and without the preheater and neither of them show a collar. Neil, do you have a photo of the Pitner lanterns burner?

    @Matty I have a slight interest in Aladdin wick lamps, but I wouldn't go so far as to say I collect them. The wife doesn't mind them inside as they are silent.

    Denmark is a bit of a third world country when it comes to pressure lamps. There are virtually no indoor lamps and the lanterns are mostly Petromax and Optimus. Indoor lighting was mainly ordinary wick lamps. Since the country is small, electricity was available relatively quickly for most people. If I go next door to Sweden there is a lot more chance of all types of lamps. Hollow wire is pretty rare, even in Sweden. There are a lot of carbide lamps around in Sweden and a few in Denmark, but it's not anything I'm interested in.

    Nice digging in archives Matt :thumbup:

    Nils - I think you are right....an early Aladdin lamp with either Burner Nr. 5 or 6, made between 1912 to 1917.
    You can spot the similarities of the pattern of the air intake on the lamp foot.
    I am interested in wick incandescent burners of most kinds, especially French; only mildly of Aladdin though.

    It's the burner that shows it is a late model 5 or a model 6 so 1913 to 1917.

    I used to be mildly into Aladdins.

    Anthony - I think you have upgraded your Aladdin interest from mild to moderate ;):)

    Nice collection btw.

    Matt. Not sure about that "Best" bit but I knew it wasn't right for a Standard-San Diego. Here's the burner from the above Pitner lantern. ::Neil::
