Army No.6 Stove

I have an army no.6 stove and would like to know more about what I think are the makers marks.
It has the letters J&F P on the side and I think a date of 85. Does anyone know anymore about these.

It is in the reference gallery, click the link above.

 

I know it's in the reference gallery, but the is no explanation to who or what are J&F P.

 

Possibly someone who does know just hasn't looked at this thread yet - it's been only 3 hours!

Or maybe we just don't know...

 

I got one of these stoves today and it is fantastic but I can't find any info

Does anyone know any more about them?

 

I know I'd quite like one, but very little else

 

Are they worth anything? Mine actually has a slightly different NSN (7310-99-138 3660) and is titled Outfit, Field, Cooking, No.6 but looks the same.

Is it worth anything as I'd really like one of the newer pump petrol/diesel stoves. That said the heat this thing generates is immense!

 

Oh but has the same alu container as pictured on other threads on this forum.

 

Does anyone know yet who J&F P are or were?

Is there a civilian equivalent to the No. 6, like the Optimus 80 is apparently the No. 7?
