Hello and welcome, others on this forum may have a more exact answer, butg i am thinking either a Ditmar, or one of the nameless German made lanterns
Hi @Michael Lindström and Welcome! That is an interesting lantern .. you could try looking in the Lamp Reference gallery under “Other Countries” ? It may be from Hungary, possibly a Szeged? It looks like some parts are Aluminium @outback boy yes I believe the tank shape is very similar to a Ditmar? Possibly other parts are alike too regards pb Ps it looks in really good condition!!
Very nice lantern! Does remind me of a Ditmar, with some differences (bail, etc). It might be a challenge to find spares, but keep looking … they’re always out there. Ulf.
That design (ceramic burner, jets, needles) is close to Ditmar from Austria, but parts are nearly impossible to come by. Imho the best is to wait for some spare parts donors, and jets & needles are produced by a Korean Ebay seller (lovelantern2014), rather expensive though.
