Hi have just acquired a 1960’s all original ES-335 in Cherry from a reputable dealer here in the UK. The guitar looks and plays amazingly. My one question however is when looking up the serial number #30040x it clearly shows it as being manufactured in 1965. The serial number matches on both the headstock and sticker. However when looking at the pots they appear to date to 67. Everything seems to be original, so was it common for Gibson to dated headstocks laying around for two years or is that the serial numbering just was less accurate during this time? Many thanks for your help and input.
