Unknown Maker (Berliner Pumpen)

This is an interesting Alto Horn by an unknown maker. It has Berliner "Pumpen" (valves) and is played lefthanded.
Unfortunately, the valves are very worn and sound horrible, which is a shame because without use of valves the instrument has quite a nice full tone. Since I primarily wanted this because of the Berliner Valves, I decided to sell it when I got another horn with Berliner Valves that was still playable.
