Hi here are some pics of one of my lanterns a bialaddin 315 this model was produced in the 1960's a realy nice well made solid lantern about 350CP these are a nice basic easy to operate and i like the preheater torch on these that slips over the vapouriser/generator tube.
This lantern is in the condition i purchased it i only changed the washers on the filler cap and it fired up a treat i have had this lantern now for a couple of years
