That said, what is interesting on this Jazz Bass is that it still is a 4 screws model, which is quite rare in 1974, but not unusual and deciphering the stamp makes it a real one: 02 means Jazz Bass, 01 means rosewood for the fingerboard, 52 is the last week (if it's not a 5, it can't be higher) of 4 so 74 and 3 is the day of the week, which is Wednesday.
If it's really week 52 and 3rd day, it means this neck was made exactly on Christmas day of 1974...
