I am currently busy with the 455 Webley series for the website and I have the following manuals:
British Service Pistol Caliber Ammunition Series 2 Pamphlet 3 (Labbett & Mead);
British Commercial Revolver & Self Loading Pistol Ammunition Series 1 Pamphlet 2 (Labbett & Mead);
Pistol Cartridges - The Webley Story - Author unknown, it is a photocopy of a 50 odd page article, publication unknown;
Notes on .455 Webley Revolver Cartridges (Lynn Harris, published 1987);
I want to scan and upload these on the website, but not sure who owns the copyright. If you do (or know who does) and give consent please let me know.
