Capri Orange, which would make that a '79-'80 International Colours J... but I don't think they had bond necks. Maybe a re-fin of an early '66?
I would have said Fiesta Red. The bound dot necks did come back for a time in 83, three bolt, with a bullet truss rod.
'66. I would think Fiesta - in one of its many variations - it sometimes leans orange and sometimes towards pinkish (and even the same one can look very different depending on lighting - it's a hard color to photographer well - or, at least, consistently). Fiesta seems really variable with age/oxidation/fade as well as if it was clearcoated or not (yellowed clear obviously pushing towards orange) and if over white basecoat or not.
Also some of the distributor refins were just approximations - I don't think they were using factory provided paint codes. The Selmer ones tend to be much more salmon pink. I suspect this could be an Australian distributor example but that's just a guess based on the grey primer (but colors and photos - is that really grey? Sonic Blue perhaps? Something else?).
My understanding is that Fiesta Red was named after the Fiestaware red - famously using uranium oxide as pigment and would register on a Geiger counter. The Fiestaware red is VERY orange - dark orange but orange. I've long wondered if the original Fender Fiesta Red used the same pigment - but have never had occasion to have an original Fiesta Red and Geiger counter at the same time
