After acquiring it at auction, the condition was poor, so I disassembled it as far as possible and cleaned it with brass soap. The original top cap was stuck, so I replaced it with an aftermarket one. The original cap and mouthpiece are also included. After cleaning and parts replacement, the valves are functioning well and there is no sticking overall, but the concerning points are the damage to the joint between the piston and the mouthpipe, and the loud piston sound. Replacing consumables may improve these issues. There are no problems with the sound. There appear to be no major dents. The case is not included. Thank you for your consideration.
