Vintage H. N. White King 2B Silver Sonic Trombone

Description

Vintage H. N. White King 2B SilverSonic Trombone is in good vintage condition. It should be refurbished so there are no dents and no tarnish or pitting on the horn. It is in as found condition. The coffin type red and black case is in fair condition except for two of the three hinges on the back side and a two inch hole in the leather on one of the corners..
On the bell it says sterling bell and 2B King Silver Sonic Made by HN White Co. Cleveland, OH. The serial number on the slide is 350421. The Mouthpiece says Bach Corp 9. The diameter of the bell is 7 1/4". I put it together and it plays beautifully if I could indeed do that.
I have tried to photograph the damage on the horn in the photos. I understand if you need more photos. If someone can tell me where to find a model number I can give it. I have little to no expertise about trombones. I copied someone's else's listing about this being a tenor horn and having a nickel finish. I am honestly not sure about all the details of the horn. It has a sterling bell but the inside of the bell looks like yellow brass. I would call the horn silver with brass trim. that means its silver and gold colored in my book. You experts have terms I don't know. Sorry.
