That was rescued from a gypsy drawn cart, surrounded by a lot of scrap. It was on it's way to the foundries. Looks like it was soldered by an accountant. When I started to clean it up, I saw that it was written Phöbus instead of Phoebus. Also, is not written anywhere when and where it was manufactured. Notice the difference in the logo design. Something that looks like a star is drawn on the burner nut. Had no nipple and when I tried to mount a new one, I saw that the hole is larger and does not have any thread. Has anyone any idea about a technical solution for this? The filler cap is borrowed from the Pragus stove.
