When I saw this I thought someone had got creative with painting it but I now believe baby blue must have been original Apart from much surface rust it appears to be lightly used no embossing ,so it may be a late one Still adjusting to the horrible colour
I have a 22 in the same colour scheme. I think the daisy style pot stands should give a clue as to age (think mine was the two plain horizontal bars). The non embossed branding (Optimus sticker) might well suggest post 1962 when these might have been branded as Optimus or Primus, possibly. Just suggestions, I have not checked. I think mine may have come with the original instructions which might give a clue as to dating it, but I cannot confirm that for the time being as it is not at home with me. Sorry for sounding so vague, but I must have bought it 20 or so years ago and havent used it for over a decade.
i got her running quite easily the right burner didnt work that well but after a long hard run it cleaned up nicely and runs like a champ now. Its my 3rd one of these. a little excessive i know but theyre a well designed thing and totally dependable, I so dont need this many but rescue the things when they turn up i,ve given 2 away in the past to family members,next project will be fixing up my campingo 2 which is the ancestor of the 22
