Getzen Marching Bugle

Description

Elkhorn by Getzen Bugle.
One piston valve and one rotary valve; Both move but the rotary one catching a bit.
The slides move.
Looks like there were some evidence of braces or something else that have been removed (I see hexagional solder footprints, but no braces or missing parts)?
I don’t know much about these horns.
I think they were used in early DCI Drum Corps as G Bugles.
Includes case with latches in poor condition.
Serial # 1095xx
