Thanks again Vic.
Steve Helsley's collection of William Powell & Son damascus guns, and the factory ledgers, have allowed us to do just that http://www.picturetrail.com/sfx/album/view/20258609
Unfortunately, the ledgers note 'Best Damascus', etc. rather than '3 Rod Oxford', etc.
The excellent pictures in Purdey Gun and Rifle Makers: The Definitive History by Donald Dallas also give a good idea as to the patterns Purdey considered 'Best' through the 1800s.
