Cluster Housing Refurb

Most of that is typical sunburn. The scar might have always been there since its in a spot not seen. So the needle goes all the way home. That's a good sign.
Do you find what looks like black pepper inside the can? Tap it on the table and the stuff falls out? Thats a bad sign.
If you have a Ohms meter you can get more info. Resistance post to post, ( I think this is a 20 ohm example ), if not 20 ohms, its 13 ohms. Open or infinite from post to can. Anything different is a bad sign.

Thanks for helping Redfish.
So here is what I see after my inspection. You may or may not be able to see in the first pic, but there is some of the black pepper in the bottom of the gauge inside. It doesn't fall out, but not good anyway.
Here are the results of the Ohm test. 3 terminals on the back of the gauge, top post A, left post I and right post S looking at the gauge from the rear.

A to I=.281
I to S=13.5-14.0 jumping
A to S=20.7
