British Military No.7 stove cases are still available from eBay seller canmec. The cases come in two grades; the cheaper GBP 10 grade is in the original cardboard box, but has suffered in storage (since 1978) from some dampness and surface rust. I bought this sub-prime grade and it is now jungle green after rust removal: The No.7 case is well made, of thicker grade steel than traditional stove cases, and the pan supports are replaceable. An excellent post by Ian illustrates the versatility of these No.7 cases: https://classiccampstoves.com/posts/149415 I wanted to use my 1939 Primus no.71 in the No.7 case as the original case, although sound, is already well used: The 1939 Pr.71 case is about 140mm high, whereas that of the Army No.7 is only 130mm. This means that the burner head sits higher relative to a pan or kettle sitting on the original No.71 case: The combination of the No.7 case and my 1939 Pr.71 still works, but I felt that a greater burner-to-pan gap would be better. I made up some 30mm high stainless steel clips from 0.5mm thick, 10mm wide strip: These are used as extension pieces. In the “parked” position they still allow the Army No.7 case to close: But once erected they increase the burner–to-pan distance by 10mm: The new arrangement seems to work well: Best Regards, Kerophile.
A very useful tip George. Funny how the best solutions are often the simplest. Luckily I bought a little stockpile from Canmec when they were £7.95 in un-opened original packaging. I assume they had received complaints about some having rust so went through the stock sorting into A and B grade. Regards, Terry
Great work George. 8) I do love an Army No.7 / petrol stove combo. The cases seem so robust compared to the standard ones & your solution to this is just like a factory fix 8) Great job Stu
get the angle grinder out .. cut a slot in top plate (as original case). makes insertion/extraction of stove from case 1000% easier . see Ians mod . Q. would the original mating stove for the No.7 case have been an Optimus 80 ? Nick .
Hi Nick, I had read about Ian's neat trick of a cut-out in the top plate of the No.7 case as per the original Pr.71. I have not plucked up enough courage to do it yet... The clips are a fully reversible change. There is something dreadfully final about an angle grinder mod. It did occur to me that the extension clips could be shaped and hinged, with single pins, so that the extensions could be folded up and lock into place once the case is opened for use... Too complicated. The original stove for No.7 cooker was an Optimus 80 tank fitted with a Svea 123R burner I believe: https://classiccampstoves.com/threads/13373 Best Regards, George
Kerophile VERY nicely done ! Not a franky or a "mod", i'm +1 w/Loco7 as I feel as though your fix is most like a manufacturer's UPGRADE of the original equipment. "AND we heard it here first !!" ...he scores! I'm onboard w/the praises: very clever, a "best" solution and simple, very useful, a great job! It's a great tip for stovies thank you for posting. edit Your fold it in-place upgrade to the upgrade not as simple BUT for the orig intent they preferred less loose pieces so for that aspect you've added that tidbit, excellent.
I thought the combination of a 123 fount and a 71 riser/burner was the ideal way to reproduce the #7 stove?
Hi Murph. For some reason he lists his stock on Ebay individually on a buy-it-now basis, even though he has multiples to sell. So if someone buys a case, the listing disappears until he re-lists it. If you want to buy more than one of anything you have to send him a message. Terry
same with bajabum here.i took a 123 and 71 apart to make a stove that fit in that case. the now unused 71 case went to cavry eventually.
George, I really like your pot supports. Such simple elegance belies the ingenuity it takes to come up such things. Bravo!
Hi, there is an optimum burner to pot distance for maximum efficiency, and perhaps safety if carbon monoxide production is a concern. Wade through this thread if you are interested: https://classiccampstoves.com/threads/13282 Regards, Kerophile.
