I still have my old L7 promag (one of JB's) kicking around. I hadn't used it in years and then got an invite to play at DF (where they only allow co2). After years sitting in it's case in the garage a bit of tri-flow and a about 10 mins over the chrony and I was sorted.
lovely bit of kit, and practically bulletproof.
