Sorry if you have already got it, but if not, you might be interested in the Cardew's book, Airguns from Trigger to Target. I don't think there is any question about how a spring powered airgun really works that they did not investigate.

Plus its in the finest British tradition of blokes in sheds, probably wearing cardigans, who really know their stuff.
