Boeing 757 Rolls Royce RB211-535E4 jet engine vane blade. Approximately 72mm tall and with a flat base, they make a fantastic collectable and displayable piece of flown aviation from the famous Boeing 757 Rolls Royce RB211 jet engine. Several available, each show unique wear from thousands of flying hours and storage after being stripped from the engine. These would polish up to a lovely finish with a polishing wheel.
