These drums are all original (I have the original front bass drum head) and are one of the most played sets in existence having been played by thousands of drummers. I acquired this set of Ludwig Black Galaxy (Pearl or Sparkle depending on which expert you speak with) 1966 drums in 2008. Ludwig has the finish listed as "Galaxy" under pearl and it's listed here under sparkle.

They were the house drums in a musicians hall for 42 years and never left the building. Their condition was one of neglect with a small amount of rust and a lot of indoor pollution mostly from dust and cigarette smoke.
Orange Cleaner and chrome polish were used and the bass drum rims were repainted. It took about 20 hours to complete the cleaning.
