Unusual Saxes

These are the more unusual horns in my collection. Internet searches have turned up very little about the brands. Most of the information that I have, has come from other players on a variety of sax forums, or from people who have contacted me through my website.
I’ve included these obscure horns here to share the information that I already have, and also in the hope that others who are knowledgeable will fill in some more of the blanks.

Evette & Schaeffer Bari
Gallotone Tenor

Please contact me if you have any history about any of these brands.
