They are cool little devices! Get a copy of TM 9-1825B - has a lot of information and is helpful to have as you work through this. I am willing to bet that this VR will work fine once it is cleaned up. Get some electrical contact cleaner and then use a fine brass brush/3M pads, emory cloth and mechanically clean them. As long as the contact areas are bright and shiny, the rest is just our collective OCD! You can try a product like Mothers Metal Polish too....if you want to go HAM!
