vanguard

I'm after a complete rebuild o-ring and gasket kit for a Vanguard Demon. It has the 2011 /2013 manifold fitted. Currently pissing air out through the body but cannot tell where it is coming from. Or if anyone can give me a clue where these commonly leak from i would be grateful. Cheers

I have come into possession of a Brushed Silver Vanguard Creed. It needs a new battery, as the one installed is swollen and not holding a charge. I knew it shot well a couple of years ago but has only been stored and forgotten about since then, I have no idea about the rest of the history...
