I am posting this stove “as it came” (and without its later-fitted silent burner) before I set about putting a NOS Primus 4000 burner on it. Found in Australia. Well used pump. Left hand end of the stamping was not firm. Steel feet. The pump cup fittings are not original. I’ll look through my spares for period replacement. A look at the pot-belly of this stove. 1911 Calalogue. [Source: @Christer Carlsson https://classiccampstoves.com/threads/1911-primus-b-a-hjorth-no-205.51578/] I need to remove the riser and re-fit a replacement #4000 burner; and see if I’ve got replacement legs (or make new ones). Cheers Tony
