Les Paul Signature Bridge Issue

[Ari Gabinet]

Hi, I am the first and only owner of a '75 Les Paul Signature semi-hollow, low impedance etc.  

Recently I have been chasing down intonation problems, and I noticed that my bridge is tilted -- the bridge side sits lower than the neck side under tension and without tension, and with the strings slack, I can tilt the bridge forward and back.  This results in the saddles actually being farther back when the strings are tightened.  

I am wondering if this is normal . . . or if, after 45 years, the bridge is worn and should be either replaced or the mounting surface resurfaced!

Tilted the other way

Here are photos of a few other “Harmonica Bridges” for comparison. I think there is a fair amount of slop between the studs & the countersunk holes in the back of the bridge.
