Hello Andre, A warm welcome to CPL ! I am sure someone will be along to help you with your lantern in the near future... Feel free to look in the lamp gallery, you may find answers there? Best wishes, Pb
The PX 2827 was a paraffin lantern mostly made of steel/iron. It's a (wartime?) variant of the 827 which is made of brass. Pre-war models of the 827 and also the 2827 were rated at 200HK, whereas post-war versions of the 827 are 250HK. Both have a Rapid torch preheater (compared with the 821 / 2821 which has a meths cup). You can find one in this thread
