“When I heard that Prince Charles had converted his Aston Martin DB6 Volante to bio-fuel, removing the original engine pistons, I knew it could be the makings of a fascinating project to give historic metal a new lease of life. I understand that these cuff links, made from those pistons, received his personal approval.”
