Wow! Thanks for all the helpful comments. So it seems my bike's history is a muddy one - I guess it's what you get from buying it from a dealer as opposed to the last owner direct.

New learnings:
1. Despite being liberally covered in Touratech stickers, my panniers are actually the TraX aluminum panniers. There will be a write-up of these in due time. I guess the previous owner bought the stupid little bottle which came with some stickers from Touratech and got busy.

2. It seems Touratech do indeed do a larger opening cannister, however, the previous owner somehow managed to get petrol into the ones I have, thus making them unuseable for anything else, and fooling me into thinking that's what they were for. It's still beyond me why Touratech bother to make a cannister which is too small for a petrol pump - I can't think of any possible reason what possible use this can have. And it also gives no excuse for the spouty travesty of a thing.

So I'm afraid they're still on 0 out of 5 stars.

Thanks for helping me learn!

haha well a friencd of my used them to smuggel alcohol into sudan:

Adventures Motorbike expedition through africa - Transafrika part 1

Good review!
I´m not in a position to defend TT, as I have had my encounters with problems with their gear (the bike of Missus looks like straight out of a TT catalogue, but I digress). However, these canisters you write about aren´t exactly TT canisters, they are available at many retailers in Germany; however TT seems to have branded some with their own logo and added a premium without making any further change :-)
Whilst I agree to the content of your review, those of us who purchase the cans new are free to use their brain and figure out the obvious at the time of purchase. Anyways, there is another can available with a wide neck. We have one with the small neck and one with the wide neck. The one with the small neck is used for Coleman Fuel for the fuel-burning stove and I´m quite satisfied with the small neck for that purpose (which is easily filled from the Coleman Fuel bottles). The red funnel fits ok to the neck, maybe your used stuff lacks a seal. However, ours are not exactly drop-proof either and I would like to see the funnel being secured to the canister by a screw-down ring.

I´m not sure why you are not satisfied with the holders of the cans, which are the real TT stuff (and are not available at the usual retailers here); ours are quite all right and we have not had any problems with them over the years. If I recall correctly TT makes them as well with a removable holder so those who dislike displaying all the equipment when not on tour can remove the holders from the panniers.

Cheers
Chris

Well, hardly a big deal is it? No reason why you couldn't use it for oil or meths or Coleman fuel if you left the top off so it dries out first. I'm gonna give these a go next time- Flexible Heavy Duty Fuel Bladder - 4 Litre

reckon you could strap them pretty neatly on top of a rear rack or pannier, even in a tank pannier, and then roll up when you don't need 'em

My guess is that the former owner of the canister would have used it for benzine (the clean stuff you also put on the old fashioned Zippo lighters) for use on a coleman camping stove or similar.
