I recently spotted a SML Tenor T400 in mint condition. I can't seem to find anything on this model Does anyone know what this model can be? It looks like a newer model with no fancy engraving on the bell (but Bell keys adjestment screws, as far as I can see). The serial appears to be 901xxx. It's a very strange bird and I'd be happy to know more about it? Is it some kind of taiwanese SML copy, or what> Has anyone played this horn?
