1980-1994 is a cool era for Guild. leftover late 70's>Gruhn-Walker>pre-Fender. On that D-25, the snake shaped headstock, with black overlay, gold peaked roof/underlined logo, sound hole rosette, and 1987 date stamp on the back of the headstock, place it square into that period. I like that the top is not stained (NT), it makes the headstock and rosette pop more and looks more like an early JF/GF acoustic, or even an F-50-R NT or D-55 NT from that era *I think* would have same rosette, or very similar (95 and later on those would abalone rosette). These guitars are a little heavy but that's what make them so magical, somehow. Guns n Roses, Tesla, Clapton, and many others played/still play Guild acoustics from that period. Anyway I can understand not keeping both when u could have something else a little different at least. I would hang onto the 77 for sure. if u sell the 87, someone is getting a super nice D-25, from a very specific (Gruhn-Walker) era at Westerly. D-25's are not so hard to find, but most Guild acoustics from 1987 are not D-25's, and would cost double-triple what you probably paid, or even more. Things were pretty high-end at Westerly in 1987, for whatever that is worth.
