where were you both when this particular guitar was debated in the epi section when i was month's old around here hahahaha! that thread got nasty. the experts in that section were sure there were no mij epi's made in the 80's despite the structural (tenon) pics.
here is a 1984 greco with the same look
1984 Greco EG Screamin 82 Long tenon SUPER Clean made Japan Vintage (409 | eBay
so they made them in 1984 too
all the best
