I bought this as I'd never come across a Czech-made version of this German brand before. Anyone else seen one? This one came out of Bulgaria via ebay. It has had a hard life! The tank has stress crack, some of which have been soldered over. The burner has also been retro-fitted with tapped screws at the top of each burner tube - no doubt to facilitate easier cleaning of the burner tubes. When I attempted to test it paraffin seeped badly from stress cracks in the tank - highlighted in the last picture by a pencil line. I decided to let it retire rather than patch it up any further although I was tempted to solder a brass patch on the side.
