    I stripped the case of a layer of non-original paint. By chance, the paint stripper I used didn’t lift the original paint or the decals on the inside of the lid, though paint and decals were well worn. I decided to re-paint the case, masking the decals and sanding the paint to provide a key for my choice of paint, which I checked didn’t chemically react with the original paint and lift it or cause it to bubble.

    After sanding and before I’d made a new ‘foot’ from 5mm section steel rod to replace the missing one ...

    When stripping the paint on the case I saw that five rivet heads were brass, which I left un-painted as an attractive feature.

    Detail, the lower back panel on this early version doesn’t have the ventilation holes of later models.

    I see that’s because later models have no ventilation holes in the base @Robert Radcliffe’s example here) ...

    ... neither do they have the ventilation holes of the earlier models in the trivet.

    Wow, fantastic job John @presscall !
    I like the intelligent "only preheat one burner" design, looks like a nice stove for family camping trips.

    Ciao, Bastian

    My Primus 77 is dated 1940, added just for information to help comparison.

    I have a Primus 77 in care and was pleased to see someone else with a similar model. I am confused about the dating. The one I have has a date code of AD (suggesting 1939) but has the later enclosure with ventilation at the back and not the top and later style of burner heads.

    Looking at the other examples in the Stove Reference Gallery the ‘later’ features arrived around 1936 at the latest.
