A great thread, with excellent view points from all! My current vintage kits (1966 Rogers Headliner, 1967 Slingerland Jazz kit and 1971 Slingerland Modern Solo) each qualify as "collector grade". My newly acquired Slingerland 1968 80N BR kit is not only collector grade, but truly borders on "museum quality". There is just no real wear to this wonderful kit and obvious that it was babied over the decades. The only thing that might keep it from true Museum Quality is that that the original owner etched some identifying letters and numbers onto the lower COB hoop of each drum and the original aluminum bass drum mount. Other than that, this 80N is as factory perfect as I've ever seen!
