Well, from a google, it seems like a nice one, though expensive at 1400EU. But, just a google search of Continental CS-1 tricone, and you'll know as much as this writer.
Hi, I did google before I posted my question, but I wonder if there is somebody here who has one...I can't find any reviews about sound and playability. I see I made a mistake... It's about the CS-N brass (duolian)...€1080,=.
Finally, my Continental duolian arrived. The brass body wasn't available, the dealer only had one style N german silver in stock, so I bought that one. More expensive than the brass one but so beautiful! Very nice sound and playability.
