The phonograph parts used on the Reginaphones were made by Columbia
Phonograph Co. The Columbia threaded end horns are fairly common as
they were used on many of the cylinder and disc phonographs made by
Columbia and also found on many other makes that were actually Columnia
products such as Oxford, Harmony and many others. Most of the
Reginaphones that I have seen had a nickle plated horn and some a wood
horn. A good place to try for a good used horn is

     Wyatts Musical Americana  in Clear Lake CA. (707) 263-5013

They are great to deal with and honest. Big stock of phono parts both
new and used. Hope this helps.
