That sounds like way too much $$$ to me...as far as Norlin-era Gibsons, my "First love" was a '77 Dove Custom that I wish I'd never parted with...as for the appeal of birth year guitars, my first father-in-law was wont to say, "A good price is all in how bad you want something"....
I had one of those square-shoulder j45's..I like it, but it wasn't my Dove...sigh...
