I have two polished Nitrous Express 10lb bottles out of my car.They are not very old.They have been taken in and out just to mark the car up and filled once.We sell these for 289.00 each.I will take 200.00 each for them.And they have the Nitrous Express pure flow valve in them not the cheap industrial looking valve..
Thanks
Dave

 

These two bottles also have the NHRA blow off fittings in them.They sell new for 22.00 each.
