Right ...if I were selling it myself, I'd say " this horn is what Saxpics refers to as a 'Kohlert-Kohlert' - although it is unlikely that is what the company called it. It is almost identical to a Regent, with a few keywork styling exceptions."Is there any way to verify other than its look that it is a Regent/Bixley? It doesn't say so on the bell under the Kohlert labeling.
I think that is as close as you would be able to get. I would not call it a Regent or Bix since it doesn't literally read that on engraving.
Unless @spike @thomsax article makes a note of the Regents vs. the Kohlert-Kohlerts (can one of you translate to confirm ?)...this may be best we can do
I like these horns....
