Some are great, others not great. I have found that they tended to have models made by them (the ones with the added C# trill and clarinet style front F) and some made by others. I had an alto that was a Courturier stencil that was like a Lyon & Healy with Martin style tone holes. What I DO know is that the serial number lists are way off. Mine was from around 1928 but the serial number came back as a 1917 horn. Go by style and features not by the numbers. The made a lot of gold plated ones and some of the gold plated sopranos are really nice. I have seen several in C.
