As with any instrument I offer, I try to keep it close to me and play it daily.
Given a good de-greasing bath, some lubes and a hand rubdown.
I have found this horn nice and easy to play with a sweet sound.
There's some old paperwork, case key and original mouthpiece and harp
Expect the usual wear and tear associated with fine old horns from this era.
One minor point is the 3rd valve top screw cap gives me a bit of a hard time
in the middle of screwing off / back on, but it's no major fight.
The mouthpiece shows no makers marks. Original case included.
See the photos.... Good luck to you...
