Is there ANY way to tell how old they are, except: - dirt - wear - color (black = not 50s och 60s) - bakelite (50s) ??? Maybe: - 3-spoke/4-spoke? - Color of the plastic (white in different shades)? - Color of the text? - Typeface of the text? - Thickness of the text? And the same question applies for switch knob and trem knob... I have NO idea. You? And remember, so far I haven't even considered MiM, MiJ etc... Pics: the black is 70s, the white are reissue (70s).
