(Pete) Yes, I'm asking.
With the other GH Huller horns here, I have at least one example that has model name engraved and a specific list of features.
I do know, from Helen's research, that there should be an Orpheus model, but I haven't found one engraved with that -- yet -- and I have these horns with right-hand bell keys.
So, convenient place to put them until further research proves me wrong :D.
