Has anyone checked out this new Ludwig serial # guide that came out last year. It's a book by a guy name Richard E. Gier and it's published by Rebeats. I bought it on ebay last year and haven't been able to stop reading it, it's that good. It's extremely detailed and loaded with info on dating Ludwig Drums from 1963-1984. I'm interested to know If anyone else has read it and what you thought of it.
Here's a link to the book If you are not familiar with it.
