Copper-alloy hoop with organic remains

Bronze hoop, diam c. 4cm. A strip of sheet bronze about 6mm wide, bent into a hoop with the ends lapped over and held by one of the rivets. There are three of these, spaced evenly around the ring: they are very strong, with solid rounded head on the outer side of the hoop, and with long shanks penetrating the bronze and going straight into the interior of the ring for 5-8mm, before the shaft is pent at a right angle parallel with the axis of the ring. Clearly this hoop has enclosed a wooden object of some thickness, but with hollow centre, for rivets have clearly been tapped over. Faussett noted wood and leather adhering when found, and thought it had encircled an object of wood covered in leather, he thought a staff, but this would not have been hollow. A mount for a crude cup or drinking horn with a very narrow neck? Unlikely?
