Not uncommon and they work quite well. You are right though they were designed on the company artists day off. The look like they were designed to get as many as possible in a shipping crate. I dont think mine has the handle of clasps which both look to have come from a similar age suitcase
Silent burners would be a good thing at least shame my optimus 22 doesn't have those its incredibly loud with 2 burners going full heat got all the seals today to get my unimet running in the hope someone may give it a home
@Garth The grid is unnecessarily far above the burner caps (compare with the distance on a Primus No.5 or similar). I can’t work out from the photos how the tank stowage works - it couldn’t rotate without there being flexi-hoses connecting the burners - or it goes in pump uppermost, in which case clearance for the pump is what might have determined the grid height.

From the photos, it has a heat shield and pivots inward ala' 8R and/or 111 series, you just had to lift the grate to clear when you hinge the fount and all inward, and then lower it over the pump et al. Right clever piece of kit when you suss it all out! Murph
