1950 Pan American Trombone - Plays but needs a little work

Description

1950 "barn find" Pan American Trombone -  Serial #205795
No model number on horn. Most likely 0.484 bore.
All I have done to it is played it for about a week and clean it a couple times.
Plays pretty good, but will need some work.
Recommend a professional ultra sonic/chemical tank bath. Finish is decent but could use some more TLC.
Bell has a few minor dents and shoulder tube bent but all could easily be fixed by any tech.
Please look at the pictures for finish and dents. Tuning slide moves freely and has a couple minor dents.
Slide is about a 4/10:
Slide has a couple dings slowing in down. One ding is in line where bell would hit slide, other is close to crook end.
There is some stocking wear. Very minor dings in slide crook.
Water key spring is strong, no leaks. (and yes, that is a home made, over sized water key cork cut from a wine bottle cork)
Any decent music shop tech should be able to remove dings, align and tune-up slide.
Comes with Olds 3 mouthpiece in decent condition. (I tried a Bach 7C and Bach 6 1/2 AL and found they both paired well)
Case is a brand new (very simple, inexpensive) replacement. Original case was very beat up and stinky.
