I wonder if i could sing the praise of a fellow BBBS member!, the man in question is Lawrie Amatruda. Not only is he a skilled man on the old gas pistols but on contacting him for advice on my recently bought Hamerli Master he posted me his own manual, i have now copied and returned. Thanks Lawrie, i think that this site is one of the best things i have found on the interneet, great bloke, great site. regards to all members from Fat Man aka Dave Payne
