Here's what the seller had to say...
Silver plated body and keys with gold plated inside bell and neck. BRAND NEW black premium pads with COPPER resonators. This horn is in a Yamaha case. The keywork is tight and this horn plays like a dream. The plating was done by Anderson Plating and the COMPLETE rebuild was done by "axetech" who has 23 years experience as a repair tech and is well known for quality work. Axetech is a charter member of NAPBIRT. This horn was rebuilt for my son, but he has moved to a M6 tenor. A whole bunch of TLC was put into this horn and, as you can see, it shows. This horn plays like a dream and will look tremendous on stage. There are two small dings that are shown in the photos.
