These are some of my favorite kinds of saxophone pics, the “exploded view” or “take-apart view.”
This first set of 4 pics is from www.worldwidesax.com. It’s the before, during and after pics of a Mark VI alto restoration. (Click on a pic to go to my gallery of that phase of the restoration.)
I’ll leave you with some videos:
This first one is a 10-part series on restoring a Mark VI tenor that had been under water for several years. It’s in Spanish, but it’s still an interesting watch!
Here’s a 4-part video that’s in English: Part 1, Part 2, Part 3, Part 4.
