Hello everybody! Can anyone confirm that the HASAG 351 L was also available in a version that used alcohol as fuel (and not just for preheating)? Some time ago a copy of a corresponding operating manual was offered for sale on eBay. One of the pictures in the offer also showed the associated lantern. A stamp can be seen on the top left of the operating instructions, which identifies the lamp for use with alcohol. Well, there are collectors who think this is not a genuine lantern. In my opinion, however, it is undoubtedly an original that was built by HASAG in this way. What is your opinion? Best regards from Switzerland! Frank
It was indeed meant for alcohol operation. Hasag made almost every imaginable stuff. Not only them, a lot of other manufacturers of the same era made similar lanterns too. Particularly when kerosene bacame rationed and pretty scarce throughout the War years. And also, everything in the pictures look genuine. I've certainly not seen a manufacturer going to that extent of making a fake lantern. Not even in China.
I have never seen a version of the Hasag 351L for burning alcohol (should then be Hasag 351SP), nor found one in the papers I have access to. The type naming suffix considers also the fuel that should be used for preheating: "A" (e. g. in 51A) means alcohol preheating, whereas "L" (e. g. in 351L) means universal fuel for preheating. Other Hasag models were consequently named with the suffix "SP" when intended to operate with alcohol. In these case they were equipped with an air restrictor and a jet with a larger orifice in order to match a proper stoichiometric mixture. I myself own a Hasag 102SP and a Hasag 252SP, but there must have been other models for use with alcohol as well.
If numbers stamped on the flap have been painted over, it may be a conversion by Eugen Schatz. Please also show the end of the J-tube and the jet.But the lamp may also have been converted back to kerosene or gasoline operation. Regards,Reinhard
It is clearly a Hasag 351L powered by alcohol.It has an extended mixing tube with a reduced diameter. This serves the same purpose as a limiting throttle. I've seen something like this on a Standard 2432 Spirit. Reinhard
This is really a unique lantern, that had been definitely adapted for burning alcohol. This is my opinion too. And the manual as well as the box could be an indication that this was already the case from the factory, although the stamping could of course have been applied later. The jet should have an orifice diameter of about 0.3 mm, unlike the gasoline/paraffin version, where it would be only about half.
