Post some pics of the tube base when you get it. There are some tricks I've read in the old-school books about handling such a thing-
1. Sweating pins to remove the base cap completely.
2. Carefully filing the glass near broken leads to expose just enough to solder stiff wire to.
3. Straighten all leads and blow the solder out of the base cap pins.
4. Then dab glue on the back of the crt and carefully replace the cap, guiding the leads through the pins.
Of course these were for b&w crts, many more leads on yours!
