I always thought that vintage headstocks look different than NS headstocks.
yes, "blonde."Maple natural SFII?
The size of the headstock changed in 1970. But, without checking, I expect the NS to match the pre-'70 so if you are seeing a difference it probably is based on the tuners.
Must have been a north-central thing since we did in New York and parts of New England. Of course they weren't always Fryes. It may have been a habit developed as toddlers since snow pants were always tucked into snow boots.Up north we didn't tuck our jeans into the tops of the Frye boots.
