I am making some research about the 5 valve single Bb horns by Lorenzo Sansone and I would appreciate any share of information about extant instruments.
I am aware who Sansone was and that he had makers such as Ed. Kruspe, Gebr. Alexander and Carl Geyer making instruments for him. I am compiling a list of numbers in the engravings (which are not always present) and making several comparisons between diferent instruments. My main interest is to try to find any difference in the instruments that would allow me to know which particular maker made an instrument.
I am also interested in Sansone's "stencil horns" marketed as Empire Models, made during WWII. Is anyone aware of an exact Empire Model of such horn?
Once again, any kind of help on this topic would be most welcome. Thanks!
