The chunk of metal is a bomb fragment, one 20mm cannon shell and 7.7 caliber machine gun cases with links. These items were picked up off the seaplane ramp at NAS Kaneohe by my uncle, Robert Weber of VP 72, days after the raid. The rocker box cover was recovered from Iida's zero by my other uncle William E. Scarborough, also of VP 72. Note the stamps inside it.
