Sonolor / Selmer ?

For the real Selmer lovers it hopefully will be easy to determine

wether if this instrument could possibly be a Selmer stencil or prototype

or just a good copy of a talented builder. You can click on the pic to enlarge it.

I hope someone can give me more information or has a Sonolor

instrument him or herself.

The first letter of the engraving anyway is promising...

In my guitar eyes this is the right bell to body connection?
A Key guard is missing and compared to the Mark VI alto
they've added an extra high key that can be opened with the
right hand pinky!

This high key is clearly visible on this pic.
Some low_bb also have this extra feature.

Arent' the left hand pinky keys in the Selmer style??

And another picture with the left hand pinky keys.

The Bell to body bracing. It looks like Selmer to me!

Another detail that could be of any importance...

SELMER SERIES 9 CLARINET

Selmer series 9 clarinet which was the top of the

line of Selmer in the sixties and seventies.

The follow up: series 10 proved to be a

little disaster comparable to the saxophone Mark VI

and mark VII story.
