Is there a list of personal firearms that John Wayne owned?

Certainly. Go to: http://us.imdb.com/name/nm0000078/filmogenre#western

You would need to access a reliable database of his entire film career. It would be a large job I think.

Try www.imdb.com Its a website called the Internet Movie Database. They are pretty comprehensive.
