I just started unmounting a Petromax 828/300 that I introduced in the collector's section: Can you help to find model (and date) of this this Petromax ?
I immediately need your help as the pump valve element seems pretty different from the "modern" ones that I unmounted in the past with a screwdriver.
I join a picture, could you help me to find out which tool is better to use? Do you know if the washer and the valve core are the same than in the modern lamps ?
Just to decide if I really want to unmount it or check if it works as it is once the rest repaired.... :-))
