Typical Pierret Stencil (model 6?)

[Noud]

Hey everyone there,

I have a Paul Beuscher alto saxophone which appears to be a Pierret
stencil model 6. It is silverplated,in good condition and in it's original
case. If someone has interest or want to see more pics feel free to
mail me. noud.koevoets@wanadoo.nl

This saxophone has a very strange keyguard on the left. If anyone of you
could be able to say more about that I would really appreciate that.

What is the keyguard like? I have a modele 7s alto with a clip-on keyguard, roughly triangular in shape, which covers the bottom B and Bb.
