WANTED: Graphophone-specific all-brass 14" soldered horn

[long_island_phono]

I have a pretty nice AG I am attempting to restore and aside from a trunnion the last piece of the puzzle is getting an appropriate horn. If possible I would like a 15" all-brass soldered horn, the type with a narrow body that I believe were made specifically for Graphophone. I will provide specific dimensions once I get a chance to measure an example in a friend's collection tomorrow.
