My dad just received a genuine US made stratocaster as a gift from one of his oldest friends. His friend had bought it years ago and treasured it and instead of sell it now that he can't keep it, gave it to my dad.
No idea what year it is but if the plastic on the dials yellowed naturally as opposed to having them be off white in the first place... this thing is VERY old.
a quick search shows that its not terribly old but it looks like its one of the limited edition models hence the intentional use of plastic that looks yellowed
