I was on the Ludwig Facebook page earlier today and saw some nice photos of Ringo's "rooftop" kit that's now on display at the Grammy Museum. I love the natural finish of this kit and have a few questions for those who have more knowledge of Ludwig's finishes from that era. Is this what Ludwig referred to as a "thermo gloss" finish? With age it appears to have an orange hue to it and I'm curious if this is due to aging or whether the original finish looked comparable? Natural finishes, at least in newer modern drums, appears to be much lighter while the "rooftop" kit is more golden in color. I know Yamaha has a Vintage Natural finish that darkens and turns more golden with age and I'm curious if this is the case with the "rooftop" kit? Finally, did this kit always have a matte look to it or was it originally a gloss finish that has deteriorated with age?
