I have played it a bit, along with his small soprano version. Very nice looking, with a sort of reform lip-plate, I think it is silver plate on German Silver, in its original case. I got myself a Bass flute by the Gebruder Mönnig factory (now part of the Adler group) and I think this whopper was made in the '70. Well, I am a sucker for these things and I always wanted to have a go at playing some Bass and Alt flute.
