Thanks for the info. I have begun the clean up process with pretty good results so far. The chrome is brightening up nicely with a little Nev-R-Dull. I think everyone is on the same page with the approximate age. I will continue to research this to match up tom mounts, finish and hardware styles. I have not even begun to look for replacement items for the set but I am guessing that the exact replacements will be hard to find.
Appreciate everyone's input.
