I am the proud owner of an Amati BBb Helicon, a B.A.H. (Bad A** Helicon...lol) similar to the one sold by the Woodwind and Brasswind as a Cerveny brand, but a few decades older. It was purchased from Herr Roland Ekle at his store, Musiktreffpunkt, in Dettenhausen, Germany, back in 2001 during my tour of duty there. At the time of purchase, I didn't bother asking about the helicon's age but since I've owned it a decade now I figured I'd ask you experts out there.
First, here's a clickable photo of it:
On the 4th valve casing there is a .14 stamped on it, to include the number 14 stamped on the bottom of each and every rotary valve (viewed when the bottom caps are unscrewed).
I've searched the Tubenet archives and have come up with zero leads on trying to determine the age of my instrument. Thanks for any info you can provide. Hooah!
