You will find this URL enlightening, it shows your shotgun in the serial range built in 1873 or 1874. See :-http://www.wrpape.co.uk/4.html
The records are held by Bagnall and Kirkwood 28 Grey Street, Newcastle upon Tyne. Bagnall & Kirkwood both worked in Pape's work and retail shop just a couple of hundred yards from the current location of the present retail shop. A potted history of the company is also to be found on the same URL. The Pape records have not, as far as I aware ever been sold. I saw them many times during the 1960's and 70's when I frequented the shop on a regular basis. If you Google the name you will find other information of the current shop and their lines stocked. Sadly English made shotguns are not amongst them unless they are guns made years ago.
