Appears to be a late Nulite Storm King model similar to one on this Terry Marsh page, second lantern from the bottom; US lantern manufacturers N - O Contact Terry about the lantern as he is studying those versions.
These lamps do seem to be Nulite however Nulite never made a lantern with two controls like this so I suspect this was possibly made from Nulite parts and a valve block from HASAG, or it could be the whole thing was made under licence. Either way an interesting piece. ::Neil::
I guess the 102SP is a WW2 spirit (alcohol) burning lantern and Hasag decal looks similar to others on Hasag WW2 era lanterns. Nulite continued manufacturing appliances in the USA until 1947 and given Nulites track record of making appliances under contract for various companies including the German American Piepgras Light company in the mid 1930s it is reasonable to think that they also made lanterns for Hasag during some years of WW2, as US manufacturers had unrestricted access to most metals until about mid-1942. Interestingly the Nulite company owner Edwin A. Kohlhase died Sept 1945 at the young age of 47 at the end of WW2 and the Nulite company was sold a couple of years later. The cause of Kohlhase death is unknown.

Hasag 102 is much earlier than WW2. I'd guess is was produced from late 1920's till early 1930's. It reassembles Nulite products very much, but there are some differences in details (some parts are typical for Hasag, used later in most of their lanterns) so it must have been made in Germany. It could have been some kind of license or maybe just a good copy. There's a German patent made by Hasag, please look into this topic: 1914-20 (about) Lux Sirius, Aktiebolaget Lux Neil once suggested that Hasag 102 could be a German made version of earlier Hasag 100 which was an imported Nulite 100 lantern. I think it may be a correct theory.
Here is a thread showing a badged Hasag model No. 100 which shows dissimilarities between the No. 100 and No. 102. http://www.siamtakeang.com/webboard/index.php?topic=5080.0
Molitor Information in the above thread discussion says that the Hasag No. 100 was a Nulite Storm King however the bayonet frame cage and bail attachment of the model No. 100 example in the http://www.siamtakeang.com/webboard/index.php?topic=5080.0 link seems to resemble more an early AGM model 355 lantern, as in this Terry Marsh example; American Gas Machine lanterns - early models
Hmmmm yes but that model 100 with a bayonet cage attachment is not a Nulite. That is an AGM lantern. At least the cage and hood are AGM for sure. No other company made parts like that. In fact that lantern looks like a slightly modified AGM 335 Dark Chaser. ::Neil::
