These are some of my favorite kinds of saxophone pics, the “exploded view” or “take-apart view.”
This first row of pics is from www.worldwidesax.com. It’s the before, during and after pics of a Mark VI alto restoration. Very kewl. Click a thumbnail for a bigger pic. There’s a link in each to a local gallery of more pics.
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!
