Gieorgi: I see what you're saying now. Today I'll take another careful look at that particular one and get back to you. i wasn't registering that you were talking about the secondary side-panel stamp. Will report soon Peter
Hi again: Just took another look and you are correct - there's the faint trace of an "I"; so 1918. The undated one has no secondary stamp. Thanks for noticing. So: to explain: I have two of these early No. 5 stoves. Both have the spirit cup on the top of the tank. One is undated and has the stamp only on the front panel. These second one which is the one Gieorgi is questioning does, on looking again under strong light, have what appears to the letter "I" stamped underneath (1918) and it does have a second side-panel stamp. So, his observation is correct. These photos were posted long ago, so the also information needs to be corrected. I can't see any edit function that allows me to go in and update the original post after all these years. PS: the filler cap is also from the earlier stove and somehow wound up on this one for the photo. The proper filler cap for 1918 is, of course, the one with vertical panels. PW
Peter I can’t seem to find a catalogue/ illustration of a pressed steel trivet as early as 1917. I get 1932 as the earliest. Do you have a reference? Cheers Tony
Tony, check again They seem to have been delivered with the "steel-Primus" initially. And as such, even in 1916 (se last image)! Here's from the mentioned catalogue No 492 of 1917: The pressed trivet was actually seen even the year before! This is from a 1916 year page I have when the new "Steel-Primus" was introduced:
Thanks, Christer: I recall seeing these years ago, which is why I made reference to 1918 as the year of introduction. Obviously around that time! P
Absolutely! I assume that the pressed steel trivets were meant as a cheap substitute to use mainly for the steel Primus they made to save expensive material back in those harsh years.
@Christer Carlsson & @abbahco1 Ha! “Boy’s look!” on my part. Thanks for pointing me in the right direction. So, the pressed steel appear during WWI, but the cast iron trivets remain illustrated on the Nos 1 and 5 stoves into the early 1930s from what I can tell. Thank you. Tony
Thank you to all involved for this clarification, fascinating stuff. I've long been wondering exactly when pressed steel trivets/pan rings/top rings* became standard fitment on Primus (and other) domestics. It's interesting to see how early the pressed steel version arrived, but how long did they exist before they replaced the cast iron version? Certainly pressed steel is standard fitment by the 1922 catalogue, with cast iron still available as a replacement/spare part. The water is further muddied here by the examples made in the UK by (or more likely for) Condrup, which were presumably fitted to save frieght costs on imported stoves, and as aftermarket replacements. Oh, and of course the big Primus domestics were furnished with cast iron until the end... *'Top ring' seems to be the official phrase used in the English catalogues at least!
