GLoux - I believe that the Stroh and phonofiddle are the same. A deceased friend had a genuine Stroh.

Within the last three or four years his brother, also a fiddler, made a trip to Tailand (I think) and found by chance some fairly good replicas of the Stroh were being made there, and bought a couple.

They came with either brass or silver-looking (some kind of alloy) horns. He offered me one for about $300 U.S. - I don't know what he gave. So, they are available in some parts of the world.
