I've been sorting out my cookers today most of them work but I have a few that r fit for spares or rebuilding. Most of the consumable parts can still be bought as they share commonality with commercially built civilian petrol cookers.
I have given a warts and all description of the cookers on the page below. The No.2 cooker was built from the late war period up to the 1980's in the No.2 modified form.

The No.2 in its basic form will run on Petrol, parraffin, kerosene and diesel.
The No.2 modified will only run well on petrol that has been my experience.
In regards to posting out I have found that if you don't mind waiting sending parcels by snail mail rather than by airmail can be cheaper. The only thing I worry about is if I ask for a paypal payment the snail mail delivery time is about two months which is outside paypals protection period for the person paying for an item.
