My Petromax 822 from Spain labelled "Venta Exclusiva A Klaebisch Barcelona Calle Claris 69". This was a challenge to get running as it had a damaged valve assembly which I repaired and was missing some parts which I borrowed from an 821 i.e. the glass, vapouriser, upper burner and control dial. I have the original vent but the upper burner has been vandalised and the one I borrowed from the 821 is a later style for the one-piece vent that is not compatible with the two-piece vent. Incidentally, if anyone has a spare J-tube and nozzle they fancy selling me I might try and repair the original burner.
