If anyone is interested Bonhams gives Westley Richards #5056 as the 1st A&D boxlock commenced in 1875 and completed in 1879 for Mister John Deeley. On the underside of the receiver is "The First Anson & Deeley Hammerless Gun Patented 11th May 1875". It would have been foreman William Anson(not John Deeley) that in 1877 fell out of love with Westley Richards and hung out his own shingle.

It appears that some Francotte VL&D's/Von Lengerke & Detmold, US Agents, New York were marked Anson & Deeley or something of the like.

Kind Regards,
