I rate the lacquer at about 75% and the horn is in good mechanical shape.This is a dual bore .458”/468” horn hence the ‘DB’ near the serial number. It creates a big broad sound. The horn originally had a very long distance from the receiver to the end of the lead pipe – over 1.500”. I installed a permanent brass shim (pictured) to shorten the distance to 1.015”.  There is no standard for this distance. Manufacturers tend to err on the side of too great a distance so that the instrument will accept a wide variety of mouthpieces. I have recently :·       * Cleaned it thoroughly, including polishing slides, slide tubes, valves and valve casings. ·       * Lowered valve spring tension. It now has very low spring tension which has helped considerably. I will include a new set ofsprings     so you can choose the spring tension you prefer. Yamaha synthetic valve oil worked best for me.  ·       * Aligned the valves. I took before and after pictures with an endoscope. I have owned three King trumpets so far. Fun toplay, and all arrived significantly out of alignment. ·       * Experimented with various gap settings. I use little to no gap. Slotting was sure at all gap settings. Intonation is good. The C# and D below the staff can both be easily lipped down, as can the G above the staff. The alignment helped even out the pitches and playability throughout the range.Kings are known for their great tone quality. This one can get very dark and rich with deep cups, like a Bach 7BW and a Schilke F3. It brightens up nicely with shallower cups, like a Reeves SV. Included is a King case which has scuffed ends and is in otherwise good shape.                                    *** Trumpet subject to prior sale - it is listed on multiple sites ***
