Large (believe 15ltr) dive cylinder was used for filling my paintball gun. been kept in a rubber boot and with a piece of neoprene dive suit around it so free of dents and dings. I have only used for surface use but brought second hand from a dive shop. Prior owner had used a few times inland and offshore twice before deciding that english water was to chilly. Not used it in last 2yrs but been inside.
Cylinder is in Swindon area. Buyer collects best reasonable offer by 10pm sunday gets it.
