    Hi here are some photos of an Optimus 1 superscript 1.
    This is an interesting later model stove. Note in particular the distinctive filler cap/air intake valve. I have an identical component on a Primus No.3 stove that I have:

    Very nice stove George, and in almost concourse condition too, as the vintage car buffs would say ! :)


    Best Regards,

    Hi, here are some additional photos of this later Optimus No.1 stove:

    You will note some unusual features in this later stove:

    A horizontal pump-tube.
    Poorer quality soldering of this pump-tube.
    Stove legs with a sheared finish at their top end, rather than the more usual squared finish on most stove-legs.
    The marking of Optimus/Primus on the top of the burner, which indicates a stove produced after the formation of the Primus Trading Co. in 1962.

    Best Regards,
    Kerophile.

    This one is very late, c. 1984. I know this because I was still buying them when new in the 1980s. The superscript 1 appeared when the spirit cup, filler cap and pump were re-designed (more cheaply, I might say). This was the very tail end of the Optimus domestic stoves (I also have an identical model with the Primus logo, purchased new in 1983, the last year I ever saw a newly manufactured Optimus/Primus).

    We've been too long without your depth of knowledge on the domestics. Great to have your back Peter.

    Thanks, Ross. Great to be back and to see so many new members and such an advance in knowledge over the last 10 years or so..and thanks for your magnificent efforts with the site - the future of "Primus" stoves is more secure than ever - also witness all the excellent new spare parts that are being manufactured and supplied - unforeseeable a decade ago when we started to unravel the mysteries of Primus dating charts et. al.

    The lower portion of the leg is also much more quickly turned out than previously - you can see that Optimus' heart wasn't much in it anymore.

    Hi, Abbahco, i believe this was one of the last Optimus No.1 models made, so I have no problem accepting the 1980s date that you propose.

    Yes, it's from the very last period - I remember buying new stoves from 1976 through 1983 - the Primus brand disappeared around 1979 (same with Svea).

    Hi, I was asked by a stove-friend to provide some additional photos of this un-used stove, which I acquired from yet another CCS friend in early 2005:
