Thank you for viewing. Pocket Trumpet J. Michael PL-350 Bell diameter 120mm, bore size ML 11.68mm This is a lacquer model similar to the 450 silver model. Both the pistons and the 3rd trigger are smooth. It retains airtightness and has a light and comfortable playing feel! After pre-treatment, the lacquer was stripped, and the unlacquered surface was further stitch-processed, brushed up, and satin-finished. Rust prevention spray was applied, and the pitch is accurate, giving it a jazzy appearance and dry sound. The semi-hard case has no issues with the sliders, and there are no problems with the handle or hinges. It is clean, with no odor or stickiness. The mouthpiece is a J. Michael 7C, a standard model. It has been soaked in a baking soda and citric acid bath for one day, and the inside of the tubes has been cleaned with a wire brush and neutral detergent to remove mold and dirt. It is ready to play upon arrival. Please consider this opportunity.
