Found this one in a swap shop, for 12,50 euro's. Spent a little on a few parts and repaired the pump valve and the burner valve with a home made rubber washer. Filles it with standard peroleum from a nearby hardware shop and now its test running outside. No cleaning has been done, the lamp is slightly tilted, I think it has been squeezed in between some stuff during storage. The year should be around 1940, but i'm not sure. Maybe someone can tell me more about it.
