Deakin & Francis Cufflinks Sopwith Propeller BMC0001C0001. The Sopwith fighter plane ruled the skies in the early 1900's as part of the British & USA air forces & was Grandpa's favourite plane. These aviation designs are made from aircraft grade aluminum. With internal ball bearings, the black cooling blades move as the highly polished, rose gold blades spin around. Even the rivets and joining panels have been laser detailed to the highest precision on the outer aluminium cases. These pilot themed cufflinks are sure to rule your sleeves! Part of the Fundamentals collection, this innovative range offers the highest quality cufflinks that are made to last a lifetime. With domed oval spring link fittings featuring the Deakin & Francis logo for authenticity, these cufflinks come beautifully packaged in a Deakin & Francis unique presentation box.
