You will find a record of Metford Patent Use Numbers in my book:
"The British Falling Block Breechloading Rifle from 1865".
First edition, starting on page 98;
Second edition, starting on page 143.
The original barrel carrying the Gibbs' name and address, and the Metford APUN probably came originally from a Gibbs-Metford or Gibbs-Farquharson-Metford rifle, dating back to circa 1880, which was subsequently lined and reproved in Great Britain, probably after it had been fitted to the Winchester action, thus explaining the later British proofs.
