Vintage Buffet Crampon Soprano Sax identification

Dear friends

Help needed to identifify oldish buffet crampon soprano sax

 

What exactly do you want to know?
It's an Evette Schaefer, already with automatik octave mechanism.
Therefor i asume it's more a later one around 1930. Maybe check on saxpics.com for more details.

 

Dear Jes!

Thank you for a good advice
And great thanks to saxpix.com for breaking the light for the stuff

It going to be 1924 to 1927 year of manufacturing
Next step is to find out if it's HP or LP as it has no stamps on the body

 

Then put a mouthpiece on and try. Buffet has 440hz, 442hz and 457.
If that thing is as sensitive to mouthpieces as my bit older curved soprano.... I cross fingers for you.
