1932. We will have a look at why the chart link doesn't work. Here's the version at CCS in the meantime.
I have quite few Primus stoves and loads of Tilleys but this is my first Primus lamp. It will probaly be awhile before i start to restore it in earnest so will no doubt come.back with loads of questions if i cannot find the answers in threads first. In the meantime, any tips on whether or not to try Brasso to polish it up?
Personally I would just clean it up with some good detergent and hot water initially and see how it looks. Often a polish just make specimens like this look worse in my opinion. Some parts will absolutely be nice and shiny, but often there will be pitted areas, and the overall appearence seems to be of the kind where it will look better clean but patinated rather than with some parts nice and shiny and others like the frame, handle and hood won't. But the initial washing up may surprise us, and tell us that a polish might be good after all. Regarding the date chart issue... it looks like it's only related to mobiles, and possibly other mobile units. It works as it should whenI open the link on a computer, but on my phone it look like below. The chart should show directly under the text "Primus date chart". EDIT: I just relalised that if I tilt my phone to landscape mode, the chart suddenly will show up! @spiritburner
Looking at the picture Phil showed , I think I do not see any text on the bottom of the frame, text saying Patent No and so on. I bought a 1020 this summer, a Z stamped in the bottom, 1935, also no text att all. Are those frames original, I do not think I have seen one before without text as Patent No and so on. Regards, Ton.
For the 1020s up to, and including, 1933 there was no text on the flame base. This was stamped on the extra plate that was fitted about the cage base. From 1934 until 1954 there should be text around the edge of the cage base. From the end of 1954 to the end of production in 1956 there was no stamping on the cage base.
Ok Nils, thanks for explaining. So my Z stamped tank should have a flame base with text. Are there no differences between the flame bases used before 1934 and the ones during 1954 to 1956, visible differences I mean?
Without starting to find all my different 1020s, I am quite sure that the overall design of the glass cage and base has not changed from 1934 on. The only difference is the removal of the text at the end of 1954. Here are links to some nice examples that show the difference. 1931 example here. 1935 example here. 1955 example here.
