Ok, I have the scales completely depinned now. When I depinned them originally I just removed the pivot pin. For whatever reason, the bottom pins were acomplete PITA to remove. I had to grind them off with a dremel cutoff wheel. Then it took forever for them to pop out. I took great care in removing them though.
Here are some pics of the freshly removed scales.

Here is a link to the full size pics and others I didn't post...
Next up I will soak them in Neetsfoot oil for awhile, then dry them off then repair the crack with epoxy.
