Flute Maker

[Monica Sprague]

Hello. I just bought a 13 key transverse flute and 6 key transverse piccolo that I believe to be from the 1800s. I cannot find any information on the flute maker however. Has any one heard of Franz Joh. Graslitz with Stowasser in larger print center?

Graslitz refers to a region, not a name, Could be a Kohlert, Johann Stowasser was found under Rampone..
Could be anything. Have pictures?
