Here is one of the tumbler posts. I have since come to the conclusion that paste Aluminum Mag Wheel polish/cleaner and micro-fibre towels are best final polish for nickle plate. http://www.vintagedrumforum.com/showthread.php?t=35545&page=2Creighton
I tried some Eagle One mag-chrome aluminum polish. It cuts right through the 50 years of tarnish. It's starting to look good. After my sax tech makes it play right this is going to be a precious horn.
thanks guys
