I'm posting here because I don't have much knowledge. Is the HASAG No. 22 a kerosene lantern? It seems there is also a Spirit type, but there is nothing written on the frame that says it is for Spirit, so this particular one does not appear to be for Spirit. In a book published by a collector, it is described as a kerosene specification. It has a pressure reducing valve and no shutoff valve function, so I also think it is a kerosene lantern, but if anyone knows, please let me know.
@Camp numao The Pressure Lamp Catalogue has this lantern listed as a 100cp alcohol lantern, but you have no “Für Spiritus” label like this lamp of @Piotrek: Hasag 22 table lamp . Tony
The alcohol version would be 22SP, and the 22 is for kerosene / paraffin or gasoline / petrol. Very handy lanterns, and almost impossible to find, except you're willing to pay a huge price for them...
@Martin K. Which model and fuel, then, is this lantern of @Camp numao? Neil’s Pressure Lamp Catalogue does not have “22SP”, so I may ask you by PM how to get it corrected. Best regards Tony
@Tony Press @Martin K. Thank you for your reply. Yes, I've always wanted it so I paid a high price. My wife asked me how much it cost, but I didn't have the courage to tell her the truth. This is what the area around the tank looks like. Please let me know if you find out anything new.
From a brief look at the documents I've found the following: 1927/1931/1932: No. 21 (lantern) and No. 25 (table lamp) burn paraffin, kerosene, and petrol, alcohol preheated, slant vaporizer. 1933 No. 23 (lantern) and No. 27 (table lamp) burn petrol only, with quick preheating (similar to Coleman), slant vaporizer. The No. 22 (lantern) and 26 (table lamp) are mentioned e. g. 1936, they have a straight vaporizer, but no pictures or directions for use so far. At the same time the No. 34 was introduced as a novelty, which is similar to the Petromax 900 "Little Baby". However, there are several Hasag lanterns designed to burn alcohol like 102SP, 252SP etc. which have this specific designation, and all of them have larger jets and air restrictors. Therefore they cannot be used to burn petrol or paraffin. Therefore I assume that the alcohol version must be 22SP.
