I really really do not know the year. 87 ish is as good as you'll get. Taking all the factors of the build into consideration, it's certainly MIJ, and it LOOKS beautiful (looks capitalized, because these are PHOTOS, only holding it and playing it can verify)
If it were string through I'd suggest it's 81 ish, but it's not. The wing headstock seems to be unusual that late in the 80's.....this is the same circular argument we get into all the time.
If it's in as good shape as it appears, I'd think going as high as 600 isn't unreasonable. Assuming you want a guitar, not an investment. You won't flip it for a profit at that price.
these are all my opinions only, which my ex will tell you are blatantly worthless,
