This originally silver plated saxophone with the

Paul Beuscher engravings was thought to be a Pierret stencil

instrument model VI. However Luthiers Vents provided 
me with some new information: This instrument resembles the most a 
Maurice (Albert) Boiste, he worked with his brother René Maurice 
who worked for Selmer before he started working for Boiste.
Just take a look at: http://www.artemos.de/boiste.html

As opposed to the americain stencils, european stencils are

equal or better (in this case) than the factory engraved

instruments. This one has more deluxe keyguards.
