Dear Mr. Eales,
I exchanged emails with Claire Guthrie of Bagnall & Kirkwood in February. Sadly, she told me that the W.R. Pape records are not owned by B&K and were auctioned off "ages ago". Unfortunately, the bidding was very steep and B&K was not the winning bidder. They do not know where they are now. It would be a great help for collectors to have access to this resource. For a reasonable fee the custodian could provide the relevant information for a particular gun.
