Another bog standard Svea No.11 here. Conforms to specifications outlined in 1908 and 1915 catalogues, and has the pre-1917 format Russian legends, but how late did Svea keep this model in production in this form? So far so good; all seems very sound and original. But then the challenges appear; first the burner tubes are clearly badly blocked up, a far as flame goes this is as much as gets through: and worse, nice though it will be to retain the original burner, the tubes are also badly corroded on the outside and one is leaking on seam: Now that, for me, is going to be a whole new level of challenge to try to sort out!
You have got some impressive stoves/lamps Ian. Have a go sil-brasing this burner yourself, you will surprised how easy it is.
'Conforms to specifications in 1908 and 1915 catalogues' - true, but comparison with other external NRV Sveas now makes me think this example can be dated more precisely to the latter part of this period or even into the 1920s. The main reason for thinking this is the inscription on the pump tube cap (see photo above) - this filler cap version is definitely from a later date than those otherwise identical stoves, still from within the same catalogue period, which had tube caps inscribed 'Nyberg Patent' (see posting of pre-WW1 Svea 11).
