Right, I found out the dates today.
Gibson purchased 2 automated winders in 1959 and so from 57-59 they were hand winding. In 61 they became fully automated as proper winding machines were purchased.
No one in their right mind would wrap wire round a bobbin by hand!
Many people call hand winding “hand guided winding” as they believe a hand wound means wrapping the wire round a turn at a time whilst turning the bobbin by hand.
Do you call hand made guitars, hand assisted? You don’t see any luthier’s rubbing the shape of a body out with the palm of their hand and scratching the routs out with their nails, they use tools just like us, In our case it’s a winder to spin the bobbin while we hold the wire between our fingers!
