This is a pure brass bearing cage that has come from a Ford GT racing gearbox.  There is ever only one of these in a racing gearbox, that's why they're so rare.  This has been buffed out around the inside edges to make them smooth and therefore comfortable to wear it has been polished to a high finish.  There are 15 bearing circles in this piece.  It looks amazing as both a bangle and also a cuff.  Clearly, it's not adjustable due to the material. What an outstanding piece of Ford GT race car to own and wear.  Perfect for the Mr, Mrs and Miss Motorsport lover!
