This is a Holton model 25 cornet in good condition. It has about 20% lacquer loss, otherwise in good shape cosmetically. The valves are in great shape and have great compression.
This design replaced the 1914 Revelation cornet as the Long Model Revelation cornet in 1924. The renamed “No.28 New Professional cornet” starting in 1932 featured an “X” bell brace in the rear. In 1939, it became the Model 25.
This cornet dates to late 1946.
