Tutankhamun's trumpets
The silver trumpet has a length of , the bronze/copper trumpet is about  shorter. Their tubes are around  in diameter at the mouth end, increasing to about  before flaring out to  at the extremity. The mouth-ends are strengthened by rings and are large by modern standards – which would have made the trumpets hard to play; Tappern needed to add a modern mouthpiece (with packing to make it fit) before his performance.
