This is a top view of Ringo's "Sullivan kit" bass drum. Ringo last used his Premier kit during the rehearsal and he Ludwig kit for the performance. Later models had a hard side cushion which was designed to lengthen the wear of the seat. In , Ludwig signed a deal to build rope drums to support World War I. The P mounting bracket features a wing bolt that screws into the casing. Arbiter said that he was so proud that he had an imported drum set from America, especially from a famous company like Ludwig, that at the time of purchase he insisted on having the Ludwig name painted on the front of the head!
