No brand - - Tuba - Unknown (No reserve price)

It's an E-flat tuba with 4 pistons whose brand I don't know.
The mouthpiece is by Hirsbrunner, which is reputed to be the best brand of all time in Switzerland.
It is silvered and worn, so you can see the gold color underneath.
It has 4 pistons.
All the slides have been cleaned inside; the four pistons work perfectly. Only one cap is missing on the 4th piston, but it is usable. It has dents but it still works.
