Stick with the paraffin stoves Graham, burn hotter and are cheaper to run, but if you want to get rid of yours PM me, I collect them
Well, I knew you collected stoves, and I did think about offering you one of my stoves in return for the double burner you offered, but...
My primus 210 I think is close to the same age as I am and have used it since I was a child, and my newer optimus 96 ( I think that is the model, its the very small one) has been with me well over 25 years, and I decided I couldn't be parted with them. I have had others over the years but they have been given away at various times.
I can light them in my sleep, and they are incredibly reliable, but my wife won't go near them and our camping "style" has changed a bit and a gas double burner is just that bit more suited to what we do (most of the time) now. I did use two 210s for a spell in a metal windscreened camp table thing and that worked well.
None the less, as I look at gas stoves, none of them have the soul of a primus !!
