Just bought this alto on ebay. Marked as Standardluxe Andrieu Frères.
After some research it seams that it is most likely an SML Rev A stencil, at least according to this site http://luthiervents.blogspot.com/2012/10/andrieu-freres-fernand-andrieu-gaston.html
Interesting to see it has a microtuner neck and a front F key, I couldn't find any other examples in this configuration.
Could these upgrades only be added to these particular stencils or could it be another make?

Ah, it is definitely NOT an SML.
I'm now 99% certain it is a stencil of Raymon Dubois Universel Superior. Found a few examples identical to a tee.
Should be a great horn either way
