This is a very early Petromax 828 I was given from a friend. I took a lot of cleaning and bending to make it look nice enough for you guys. Here she is:
The bottom shows the scratched numbers 8 6 which stands for 8, august and 6, 1936. There it is also posible to see stresscracks luckyli only located to the bottom. So she will be a shelf-queen. Claus C
The first time I met the "Scratched Numbers", Martin K among others, helped sorting out the meaning of them and it is more and more clear that it actually is date-marks(not hickeys) and certainly worth paying attention. Here are some of the links: (Edit: three links that wasn't working removed) http://0flo.com/index.php?threads/6462 Petromax is a primeval lamp and deserves to be arranged the same way as the Colemans and Optimus. Petromax is made in so many models it would be nice to see the pile in neat order to my humble oppinion. Claus C
Nah Karli, I took of the preheatertube to show the jet too. You can see the tube on the other pictures with its lightninghole Claus C
Hmm strange Martin - I just copyed it the usual way - but all 3 links is to be found here: http://0flo.com/index.php?posts/34912 Yeah a lamp from 1936 with that much dirt and slime in the tank must have had the jet changed more than once so someone put on a 350 though the tank is printed 300 CP Claus C
Along with this one, a 826 followed. I just cleaned her up halfway and found the numbers in the bottom to be 11 - 3-ish, so that makes the 826 a nowember 1933 or 1935 or 1938. But I will be back with that miserable lamp later Anyway a lamp starting with 11 shows it must be the month firs as Neil also says and the year afterwords. Claus C
