Taper thread screw valve for trade

[Max]

Hi,
I have a taper thread screw valve which I think fits older as newer fire extinguisher bottles, unfortunately I need one with the M25 thread so if anyone has one which they want to trade that would be super.
Also open to offers on the valve if I can't trade it.
Thanks,
Max

This is still available for sale or trade- also I am after a 1kg co2 bottle with an M25 thread- the one I've got has a taper thread which fits the screw valve.
So ideally want to trade a 1kg bottle with valve both with taper threads for a 1kg bottle and valve with M25 threads.
Also seem to have about 3 variations of 2kg co2 bottles which I would happily trade (most are the normal type, a few are a bit longer and thinner, and one is very thin and much longer) and also have got many water and powder bottles which I could trade.
Thanks,
Max

Turns out that the 1kg bottle I've got should be alright for my needs- the thread isn't as odd as I feared like most these threads are! So I am just after a screw valve with m25 thread. Happy to pay for it or trade my valve or any of the bottles I mentioned (other than the 1kg one) also got other spares I could potentially trade so if you have a valve and have something in mind you want for it just let me know!
I know this should be in wanted section but I doubt anyone wants me to post same thread in wanted section.
