Mark Levinson - how to fix white logo paint that has peeled away?

I used to sell and mix custom paint colors and there are a thousand different shades of white.  Each one had little bits of yellow, black, red...
Whatever it took to get the desired shade.  You will never match it exactly without knowing the precise paint code.  That said, I would leave it alone.  Just tell people you have a Mark Levinsor amplifier.
