    Does anyone know what this is?

    Tank is about half a litre, marked with "Alpha" and underneath "GB" - Gustav Barthel. I think it runs on ethanol, and the air mix is adjustable with the vertical screw in the middle, which I can raise and lower to get more or less air. Opening for fuel is the horizontal screw which goes through the tank. Pressure gauge on the top works good. The little black thing on the fuel lid is a short hose which I put there to fill air with a compressor. What was it used for ? Have never seen anything like it...

    Hi, I have never seen one like this before. However, there is a Gustav Barthel catalogue in the Reference Library (accessible to CCS Subscribers) which shows laboratory burners:

    https://classiccampstoves.com/threads/barthel-laboratory-burners.10766/

    The model you show is not there, but there is the "Neukryolith", approx. one-litre Benzin/ Benzol-powered laboratory burner which has some similarities to your model. This catalogue model has a built-in air pump on it's tank. It also seems to have seven interchangeable burner heads or burner tubes which can be connected to the burner base.

    Hope this helps,
    Best Regards,
    Kerophile.

    Is there any particular reason why you think it runs on ethanol?

    The size of the nozzle, and i tried it with both eth and petrol, and with petrol it had a soft, smokey and sooty flame. With ethanol the flame was short and blue, but it only worked for a few seconds, it was garbidge in the nozzle. I have cleaned it now but not started it since.

    Sorry, I can*t see that link. I also thought that it was a lab burner of some kind, but what a complicated construction... I wish I was there when they made it, and could have a peek into their brains !
