From what I’ve read this would be a late 1930s model 827E. Sadly most of the plating has gone except on the collar and the enamel top is past saving. Wrong knob, no globe although I think everything else is there. I wanted to record it here but will try to sell it as is.
Some great info about Petromax lanterns on this site, I just use my phone and the translator Petromax 827 E - 250 HK Petromax 827 E - 250 HK The Petromax 827 E are early post-war lamps, built until about 1954. What the "E" stands for is still unclear, one guess is that it could stand for "export". Technically and visually, the E-models are in any case no different from the other 827s.
I know very little about Petromax and will leave it to the experts, but I believe the parts on this lamp are all pre WW2.
Nor am I @Nils Stephenson but I’d have to agree with you. There’s reference to an 827 baby, which looks to be 200 HK instead of 250 HK. It looks to say 200CP on this lantern, so perhaps this is some kind of 827E ‘baby’? Purely speculation on my end, I’m just interested! It’s a very nice lantern! Petromax 827 - 250 HK
It looks great. As it is. Yeah, pricker knob might not be original but I think its still an early one. Looks somewhat like some of the earlier Optimus knobs.
Possibly Export but the E models both pre and post WW2 turn up in the UK and I wondered if it could be England? Do these turn up anywhere else? If E is Export then they should be found all over the world and as far as I know they don't. Most Petromax found here in the mid to late 1930s were Aladdin Petromax but I was recently reminded they were also sold by Falk Stadelmann and I suspect that is what the E types are. ::Neil::
@Jean J Your Petromax 827E is of course a pre-war lamp. The black handwheel is from Hasag. Unfortunately, I only own post-war lamps of types 821E,826E, 523E and 827E, 828E, 829E. They all date from 1953.The associated instructions for use are also from 1953.As far as I have observed, Petromax marked the six types mentioned only with an E in 1953.There was no Petromax in 1953 without an E. Most of the Petromax lanterns from 1953 marked with an E have a mixer J-tube attachment on the side. Some Petromax 828 E's were equipped with gasoline carburators and some strange pin in the J-tube. 1953 is also the last year in which the E in the G could be seen on the tanks for the last time. I am sure that the E has nothing to do with export. Regards Reinhard
