Hello I've come across this Primus no71. There is no stamp at the bottom. Does anyone know what year it was manufactured? Kind regards Marcus
@Mackah Designated ‘71E’ with that windshield/stand. Not in the photos (missing?) are an aluminium pot to store the whole thing, a lid/frypan and a pot lifter. 71E’s were marketed right up to the mid-1950’s but looking at the stove and fuel cap pattern I’d say that’s one from the late 1930’s. Closely resembles mine, featured HERE. John
Hi @myford well made video. How hot does the tank of your Pr.71 get in use? You seem to have only limited air access to the enclosure. Home-made windshield/case for a Svea 123 Best Regards, Kerophile.
Hi K. The tank gets pretty warm but not worryingly so. Not too different from other self pressurizing stoves. I wish I had one of those non-contact thermometers to check it. But since it does seem to be industry consensus to include a barrier above the tank my tomato can system does include the option of doing that. I have a stainless shield that fits in there at a small penalty in awkwardness. I can post it next time I take some pictures. Cheers
+1 with twoberth. So very clever. TY myford. I think it wise to integrate a heat shield with ample air/heat flow through, credit kerophile link. ---------------------------- Re OP: Thank you @Mackah for posting your 71 and including the detailed pics. Congrats lucky man, that is very nice. Re your question: "Does anyone know what year it was manufactured?" As shown in OP it is a Primus 71D, 1931- c.1932 (an accompanying pot & pan makes it a 71E) re 71D: I explain 1931-37 71D, 71E & 71L here. All members are great don't get me wrong but non-subscribers can take my word for it, these kits are offered in 1931 to 1937 Primus catalogs, here is link to such a 1931 offering (in, subscriber, ref. section). re 1931- c.1932 Yours is a 1st version Primus 71, as shown in OP w/your specific parts in place.
FYI: there are many versions of the Primus 71. Narrowing year ranges for "what year" an example was made is an ongoing challenge. To-date I gather, re early undated examples, there are 4 versions of Primus 71 1931-37: > 1931- c.1932 1st version Primus 71 then a > c.1933 / c.1935 Primus 71 version then a > c.1936 Primus 71 version then in > 1937 Primus 71 date stamps began. Corrections & comments welcome, certainly re dating & dating terms. TY
Regarding the (absent) heat shield. That is an "undocumented feature". The can has some small slots to accommodate mounting a heat shield. As seen mounted here: There are air gaps on the perimeter of the shield to permit air flow from the lower part of the enclosure to the burner section.
