I have the opportunity to buy a Mark I red sub from a reputable guy and he describes the dial as becoming "dark brown." Hard to tell from pics but has anyone ever seen a dark brown dial on a Mk 1? I read the article about red subs from Mark L and he has a disclaimer that it is obviously not gospel but it says brown is only on Mk2 and 3. Just wondering if it is possible on a mark I?
This is my first red sub purchase and don't want to mess it up!
