Another Sunn in with similar issues to the other one. However here the bridge had been screwed down tot he body so tight it was leaning forward on the beveled part. As it turned out one of the screws was actually a scratchplate screw so I swapped them for hardened steel ones. I added more springs and blocked the trem off.
Needed some work to the nut as this one was detuned to drop C and had some fat Ernie Ball 12 – 56.
