I just traded for a Strat, that has no visible serial numbers. I'll post pics tomorrow, but it has the Logo in gold, trimmed in black, and Stratocaster in small black letters, with syncronized tremelo, and below that, patent numbers. On the "ball" of the headstock, "Original Contour Body. There are also 2 string retainers. I have read that it is sometimes necessary to remove the neck for numbers, any ideas what I have?
