Hi just to ask I've got a bsa spitfire here which I've had a while now and I give it a few shots at least every fortnight or weekly on times, All seems great and doesn't lose any air etc, Just wanted to know as I've got a 400cc buddy bottle spare now without valve which was used on my rapid could I buy a bsa valve to fit the 400cc buddy bottle to then use to fill my spitfire, Is there a specific bsa valve for the spitfire or will any of the super 10 / r 10 valves work, At momeht im using my dive tank to fill the spitfire via a adapter, Thanks,
