Hi, here are some photos of another Primus No.10. This one is marked AD24 on the base of the tank, so dates from 1939: The above shots show the stove operating at high power. The burner is however very controllable and the two photos above show the stove operating quite happily at lower power. The No.10 stove uses a bigger burner ( No.4140) than the No.5 stove. I estimate that the 4140 burner has a maximum heat output of about 3.4kW, or 11600BTU/h. This is about 20% more than a Primus No.5 stove burner. Best Regards, Kerophile.
Hi Trevor, I am glad you like the stove. I was lucky to get one of the last available outer caps for this burner from Base Camp. As you can see it produces a lovely flame pattern. I think that a fair number of these No.10s were sold in the UK at the start of WW2. Presumably people were preparing for fuel shortages and perhaps loss of Town Gas. Best Regards and Seasons Greetings, George
Hi Kerophile,, I just got this Primus #10 date coded AD24, but it does not have the 4140 "large" silent burner with five rows of holes on it , but the "standard" silent burner size with only 4 rows of holes in cap . When I say "standard" I mean the same size as my Optimus 5 silent burner and my hipolito 36 silent burner, did they come in two different sizes for the #10 ? Aslo did it come originally with a pot-rack ? Cheers Tom
Hi Tom, The Pr.10 had the larger burner as standard and as a result produced about 20% more heat on full power than a Pr. No.5-type burner. However a lot of Pr.10s appear with the slightly smaller burner and it may be that people fitted these when the larger ones became difficult to find. To answer your second question, Yes, the Pr.10 would have originally come with a pan-holder. Hope this helps. Best Regards, Kerophile.
Hi Kerophile, thanks for info , unfortunately I was hoping to get a "big" head burner like yours, so I guess I'll have to look out for a 4140 burner, fat chance uh ? , and a pan -holder too. It's a nice old stove although, it fired right up after replacing pump leather and washing out tank, a little carbon in burner, but I'll clean that up and it should be a great user stove Cheers Tom
