@z1ulike I'd already ditched my earlier proposition about the purpose of the cut-out in the heatshield Ben, in favour of it being to provide clearance for a light attachment as your No.42 has, but neither do I think it's for access to the fuel cap for refuelling with the stove in place in the box. It would be very awkward to refuel that way because the stove needs to be removed from the box to easily unfasten and tighten the fuel cap. Besides, the cut-out was already there on the earlier models with the fuel filler cap in the base as with S. Molson's Radius, which has the clip for the attachment in the drop-down flap, though not equipped with the accessory in his particular example.
@presscall I see you are on to the similarities with a Radius tin, and explained most except the purpose of the cutouts/inside storage loop on the lid. I cannot say exactly what this is meant for, but I have seen those a couple of times; one had a small bottle/vial for spirit jammed in it. I do not think I have seen only the lid cutouts on a Radius tin, but some time ago I tried to acquire an 80 here in Trondheim. That one had a plastic cable tie in the lid, so it had cutouts. I have also seen a small cylinder with spare parts (jet/seal) that might have fit in the loop, but this cylinder followed a Primus No 71 (not a 42 or an 80). There was a filler cap seal in this cylinder I at the time thought was for a Radius No 42; there is my connection. This is all vague memories and speculations, but I figured I should report as my memory was jogged. This stove going over the auction block recently, is much the same as the No 80 this started with. All the best, e
@tofta That's really helpful. Thank you. Amusing to hear that someone had made use of the empty slots to take a cable tie handle. @kerophile had suggested they could be handle slots I've the Radius with the loop in the case lid that I pictured earlier on its way to me, so I'll be able to think more on what it might have been intended to accommodate as opposed to the uses to which it's been put. A spirit bottle's a good contender, but Radius instructions for lighting advocate using the fuel in the tank to prime with, so maybe not. Matches rolled up in a piece of oilskin cloth would be my choice, but the manufacturer's intention? Thanks again, I'm most grateful. John
These little details are fascinating, and the solution is often a practical and useful one. I cannot think of any case were the stove makers added general purpose loops or similar for stowing extras (though there probably are examples). So I would guess it has a specific purpose, the potholders also bends around in a way making room and helping keeping whatever is held there in place. Matches are definitely handy for lighting a stove. I have never seen the extras stowed on the front panel (possibly the lamp thing), so I could not say if any of those parts would fit. Other extras are few; there are funnels but cannot see how they should fit. The solution is always out there somewhere, so much information is gathered on CCS but more questions keep popping up – definitely fascinating. All the best, e
Great Stove! I have a question, how do you go about removing the vaporizer on this model as there is no nut at the bottom like on other models of this type of stoves ?
@Duran Wood blocks, nitrile sheet packing, G-clamp, as on this Optimus 8. The Optimus 8 stem accommodates blocks of that pattern (hole drilled in a block that's then halved), something like the Optimus 80 here would require blocks with a portion carved out to roughly fit to shape - or use softwood blocks and they'll crush before the brasswork does.
@presscall Hi John. There was a thread about that loop: https://classiccampstoves.com/threads/radius-42.34545/ Cheers Enrique
@shueilung.2008 Hi Enrique. I know, it was one I started when I got a Radius 42 that helped resolve the mystery. It's to hold a ski-waxer accessory torch. John
@presscall BUMP with very late update. I concur with *"early 50s" and I post now to also suggest this "new" ver. OP 80, was 1st to use: > new 1/3 pt tank (smooth shoulder, vs predecessor 1/3 pt has ribbed shoulder) > new tin > new 298D filler cap (298D also debuted w/ "new" no. 111 in 1952) > new key with notch on side to accommodate 298D filler cap's SRV [TMI: 7 link key chain] ------- fwiw 2022 Dec., me:
