I’m visiting my parents and bought a battered Primus 96 at a local market today (Sadly it turns out to be beyond my ability to repair). I have a couple of other 96s including a nickel plated example which I happen to have with me. The brass one I found today is date stamped for 1935 and my nickel version is from 1936 so the stoves are a similar set up. My nickel 96 has yellow tips to its flames even after servicing. I suspected a worn aperture on the lipstick vaporiser so I decided to take the opportunity to try out the burner assembly from the other stove. Lo and behold it worked much better! However when dismantling the stove I noticed the lipstick vaporisers are different from one another: The one on the right is the one that came with my nickel stove. I know the nut was usually plated on these so I’m not sure if it has worn off or if it’s a replacement. The one on the left is from the stove I found today. both are stamped ‘Primus Sweden’ and the rest of the burner assembly on each stove is identical. The brass nuts are quite different shapes, they also each have different stamped codes on the rear. Does anyone have information about eras of each of these? Is one likely to be a replacement as the stoves are only a year apart in age? I’m sorry if this has been covered elsewhere on here but I couldn’t find it.
Correct for the stoves, I have one or two with that vaporizer. Too many 96's to narrow down which ones, could check dates you have. Duane PS: neither of mine from those dates have that style vaporizer.
