    Another trusty workhorse of a stove out on duty rotation as this week's daily user. The full weight and full size burner big brother to the lighter weight small burner 1915 No.5Jor. Features the same low, fixed, auto-lighting spirit ring; which does work as advertised, but can also be a bit smelly in the priming phase which maybe why they were eventually dropped from the range. Notice also the short-lived Primus version of a mickey-mouse ears filler cap and the early 1920s type, replacement, burner.

    The low-spirit ring auto-light system shown and linked to above is a little problematic. Yes it does work, but it also has its limitations. It works most reliably in conjunction with the clip around draft shield, to assist in funnelling the flame up to the burner, and with the pan or kettle already pre-positioned on top. The fact that it is still smelly in the priming phase I think probably was its downfall and the reason for Primus eventually switching to the tubular clip-on lighting assists. These latter, however, like Svea's rather more effective deep reserve dimple and flame leader combination, were not true auto-lights, you still had to go back at that last second to close the pressure screw and start pumping before you missed the moment. The only really successful light and walk away auto-light system I have found in practice was the set-up on the Pyro Patent stove.

    Interesting to have that user experience Ian. Makes sense what you say concerning the concept being shelved.
