British? You mean like this one? 1982ish Ron Cooper. As pictured, Campy 10sp triple drivetrain.
It currently has a 7sp triple friction drivetrain (mix 'n' match, Suntour VGx RD) and Suntour brakes. I rode it in the 2019 Eroica California Pedro Blancas route (pictured below with kabuki12). Fantastic bike.
