I just saw this. The backwards "primus" gasket is on the fuel tank cap, not the spirits tin. The spirits tin has a cork or fiber gasket. I've placed the original spirit tin in the display case and replaced it with a reproduction tin. I'm not going to risk damaging it.
What I didn't say explicitly in my post was that the completeness of this '41 example suggests to me that it's not gone missing but that the heatshield seen on some examples wasn't always an original fitment. Having used my silent burner-ed '41 extensively, I'd say it's not needed and it's of interest to me that I probably haven't had a heatshield go missing either.
That's good to know, John. @presscall I was thinking of making one, but now maybe not. Do you think the nickel tank does a better job staying cool than raw brass?
You know, I think it well might do. Unless the brass is newly polished it'll more often be tarnished and (I guess) less effective at reflecting radiant heat, which is mostly what a heatshield is there to do, since it won't have any impact on cutting off heat conducted through the metal. Your nickel plated tank isn't going to tarnish as a matter of course and is likely to be a highly efficient reflector of radiant heat. Well, that's my reasoning! Theory aside, as I say I've never had any cause for concern with my '41's brass tank getting too hot and it's rarely been polished, as a favourite stove to use and not just to look at. John
Good stuff. Yes, It's going to be a user. I used mine last night just to make tea and process my bacon grease. (Double boiler to melt grease and strain off the crusties...)
@Billyboy , Your No.41 certainly appears to be original and complete. #1 thing I say is more detail will become known with more "Primus" references and stove examples 1939 - 1950. For now, given what is available here to-date re No.41, 341, I find: *1939 Not offered: stove No.41, 341 1941 No.41 w/kerosene burner, YOUR STOVE, a solo reference, thank you. 1944-51 No.341 w/alcohol burner (Stove No.41 not offered) 1952 No.41 w/kerosene burner (Stove No.341 not offered per catalog) 1952-56 No.41 Examples in SRG. 1955/56 Not offered: stove No.41, 341 (per catalog) Given *that, 1941 is early and it may be "1st year". I may have missed something but if not, it could be said (again, to-date), 1941 is the oldest example of No.41 (it IS "truly amazing" aye). It's also maybe the only pre-1952 kerosene example. Per '52 catalog the case is 8 x 7 x 4" btw. BURNERS... in 1944 we see No.341 uses a 3026, it was said above yours uses 4155. Under TMI the 1944-51 uses 3026 a version of 3025 type burner. Myself, I suspect yours uses ???? a version of 4155 burner. A difference being the folding valve stem, possibly? (w/all other parts same as 4155). Heat shield , being a kerosene stove I too doubt it "missing". The makers maybe did consider heat shield option. In this exact same meanwhile 1939/40 Primus DID sell an "option" of safety release tank lid. Notes: a. regulated burners are often paired w/safety lid. b. yours has no vent nor srv lid (one might like both?). thx omc TMI beside the point but need for search tags: from here c1940 [burner] "No.4155 with the extra spares No.4241 (spirit cup) and No.4355 (connection tube)" ... and ya heard it here 1st.
Hi @Billyboy , you have a lovely stove in great condition. Have you wondered what all the metal loops on the outside of the case are for? Look at this illustration from a 1944 catalogue.
Thanks George. @kerophile That's so cool with the straps for the bicycle. I saw that on another thread. I made a video showing the stove in operation.
Thanks guys. I was thinking of posting a new thread with the video. Would that be "attention-whoring"?
