Yes thanks for that info, I did have a bottle adapter here but I've either give it with a load of parts I give with the other guns I sold or I've put it somewhere, One of my other buddy bottles is leaking but its a different type and that will empty over time if I need to change it, That one may even be serviceable but not sure what one it is apart from it being a white plastic valve and the bottle neck has cut outs on side so a spanner will fit it to undo,
