Found this old treasure at a local sale....It is a vintage..tarnished Revelation Trumpet made by Frank Holton & Co.  Elkhorn Wis.  Serial number 112674....the chart i looked at put it at 1932...that may not be correct...it has a hero mouthpiece and a baffle etc...it has original case but it is rough as shown..  I blowed through it and sounded like a dying cow...all buttons go up and down...front and back seem to be ok...middle one has slack wobbles freely but spring is in there .  This might be cleaned up and refurbished to play again...idk....I'm just listing in parts non working category. .no warranty..no returns...bid accordingly.. buyer pays 45.00 S/H......to lower 48 states..thanks for looking.
