Not a ‘frumpet’

@Newell-Post

I have one of those Eb/F Getzen 300 Alto trumpets. (Not a trumpet).

Although a conventional trumpet mouthpiece seems to fit the receiver perfectly, this is a totally unplayable setup, with terrible tone and no apparent resonant notes at all.

Yesterday I discovered that my Eb tenor horn mouthpiece fits perfectly and transforms this beast into a musical instrument. … sort of.
