@shagratork I’ve just received a Svea 51 (curtesy of @Rodger Willows - thank you). I will post photos in the Reference Gallery some time much later, but I will, later today use it to answer a couple of questions still floating around about the Svea Nos “50” series of stoves. I will also spend some time going through your excellent spreadsheet. My question to you, though, is in your above analysis where you post the table showing the various models and their configurations, what is the difference between Nos 54 and 55 versus Nos 56 and 57? Is it that alcohol is the fuel like in the Nos 150 series for models 156 and 157? Tony
@Tony Press Hi Tony I had never intended my post to be a definitive work of the 50s and 150s range stoves. When I posted it I still had a lot of unanswered questions. I think a number of new ideas emerged, but I can't remember them. Maybe it is something I should return to - when I have time! However, to your specific question. As far as I remember the 56 (left) and 57 (right) had the silent 1715 regulated burner for paraffin. The 54 (left) and 55 (right) had the silent 1815, then later the 1915 regulated burner for methylated spirits. As always, others may know differently. Regards, Trevor
I have recently bought what I believe is a Svea no 57. The burner is a type 1715. The outer cap of the burner was missing. I have fitted an Optimus outer cap as a replacement. It works :-) The fuelcap functions as an ordinary fuelcap with screw, but the "screw" has a built in SRV. Within the fuelcap you might spot a tiny tube, the point of the "screw". The pumprod fitted at purchase was actually the rod of a Høvik Verk no 41 without the cap/tank top cap. The rod is to short for the Svea pump tube. By pure luck i have a Høvik Verk no 41 with what i believe is a Svea pumprod, a bit to long for the Høvik tube. Judging from the other pictures posted here it seems to be the correct one for the Svea stove. i did the switch between the stoves. Bothe rods fit like a glove. I do not know if the box is original, but the wooden brackets on the underside of the lid fits and steadies the pot stand during transport. The previous owner had shifted the regulating handle from the left to the right side. The right side turned out to be the wrong side. With pumprod and regulating handle on opposite sides, the stove did not fit the the box. This was solved by making a hole in the side of thye box for the pumprod knob. Easy fix? I shifted the handle back to the left side. Now the stove and the box fits. Feel free to comment on the box or the pumprod.
Re Trevor's: > I would also appreciate any further contributions. RIP considering his: re FRAME: The earlier 50s series stoves (early 1930s) had this [earlier] frame. **more below some of the 50 series of stoves had the earlier frame. ... all the 150s range of stoves had the revised frame. BUT ... some of the later 50s series stoves also had the revised frame. and re TANK: All the 50s series stoves had a one-piece tubular fuel tank with two circular end caps, **more below. and re SRVs: The earlier of the 150s series also had a screw air release, although it was different to the 50s series stoves' screw air release. ...The early earliest vented filler cap Trevor shared is early 30s ver. of pn 1891, *more below Later 150s stoves had a SRV (Safety Release Valve) built into the filler cap. There are three main types, two with a circular hole and another with a pentagonal hole. I am assuming... assuming The earliest SRV filler cap Trevor shared (**same caps used on Sievert Svea 123s) 15060 upper portion of cap is round with small circular hole on top. the next ver. would be 15060 same as prev. but upper portion has 2 flat sides (for spanner) same sm. hole at top. next 15060 reworked, a fitting screws into the top, this ver. fitting/screw w/pentagonal hole at top. **as year ranges get narrowed for Svea 123 filler caps, the same likely applies to dating the 150 series. Note Wilhelm's filler cap above (no PN), if original, is a more than just slightly interesting finer detail and something i can not understand (misprint?) is 1956 Svea Product Catalogue listing PN 1881 (????) as filler cap for 150, 151, 152, 153. "By 1956" i would have expected a ver. of 15060 (15060 is correctly listed for the Svea 123 on SAME list. The cap they list is not the earlier vented 1891 (carried-over from earlier list... it shows 1881 ? This sure seems like a mistake to me for now, was 1881 ever even a Sievert PN?) ============================ *Re Trevor's early 50 series from early 1930s; the illustration in 1937 Extracts - Meyer Catalogue still illustrates an unchanged example in 1937. Catalog "illustration" is not confirmation but that is one indicator that from early 30s - into 1937 the 50 series may have remained unchanged. ok. Reminder: "... last i knew it's not yet clear when 50 series ended and 150 series started". ----------- *and consider 1 interesting example (for now), a later 50 series SVEA 52 if original (odds are it is and it fits). This later ver. of 50 series, a Svea 52 shows us snapshot of model development details with: later revised frame with [later] the new drip tray... with strengthening ridges early tank, also NOTE still has "PAT. APPL. FOR" and still vented filler cap, it may be the next/later ver. of pn 1891 Trevor made mention of (vs the earliest cap). Here's a pic from link thx 9,650 views
oops, the most recent example posted is why i revisited the topic, doh. At a glance the dating details of What 50s model Svea is this? are also a match to the 52 example I feature above (incl. early "PAT APPL. FOR" tank). I DO note one difference, no PN on vented filler cap. there, i've said too much, gotta run edit PS: in-general stoves that come w/valve/regulated burner might also come with SRV filler cap. I'm not aware this applies to 150 series but figured I'd mention it... thinking it may be indirectly related to: when or why SRV cap got incl. w/150 series? and may help explain (my) filler cap PN confusion in '56 catalog?
