I haven’t found a selective single trigger that was something I warned to own. English, or, otherwise. Non selective single triggers seem to have been less problematic in my orbit. But, less useful, in theory.

Good luck.

Percy Stanbury’s gun was made in the 1920s long before the first 700 came out in 1949. It was most likely a 400 series shotgun.
