Hi Rob M
In the eighties in Guns Review a contributor did a series of patent articles with patent numbers and a short description of the airgun. At that time if you went to Birmingham City Library you could go through the catalogues of patents. If you wanted a particular patent you asked for the Year in question and would be given a book about sixinches thick to look through. You could then ask for full patent and take a photocopy. One of the patents shown was the Whiting. Another was an air rifle made by a A.W.Baker in the article it was said that no known examples existed, a couple of years later I bought an unknown rifle at auction, John Atkin identified it as the Baker from the patent article. If you interested I can post photos of the Whiting and/or the Baker.
