Luke III Vintage Tremolo Edge Wear – How much is acceptable?

I tried to love my 2012 Luke III with .009 strings on it, but it just wasn’t meant to be, so I’ve gone up to .010 strings. Before I put them on, I figured I’d finally take off the trem and really clean all the nickel plated parts, and check on the condition of the edge bearing.

There definitely is a little wear, and the plating is off, but it doesn’t seem to be major. I have not have any problems with the tremolo returning to pitch, even with some serious abuse. I did lubricate the pivot points with some Tri-Flow to keep things working smoothly. I bought it used, so I don’t know how much whammy action it got from previous owners. Just want to make sure it’s in good working order.

I’ll try to get some pictures of the edges later, as I unfortunately for got to take some.
