Wal-Berg Concerto

[trp.marco]

Hi everyone, I'm new to the forum, I'm Italian and my English could be better.
I am a former trumpet player, now a teacher, putting my archive in order I found the trumpet part of the WAL-BERG concert that my teacher had given me. I looked for piano accompaniment, but it hasn't been in print for years ..... if any of you have it could you please let me have it? it is a fond memory of my teacher and also of that pianist who did not give it back to me, thank you
