so far, still can't be 100% its a J45, not sure how one can tell other than measurements if its a J45 of LG series from this period.You're the winning bidder? Nice score.
I'm seeing several cracks on the top and back, presumably from being dried out in the Arizona heat / humidity (or lack thereof)
But a good luthier should be able to put it right quick enough. A session hydrating back up, patching the cracks, probbaly need to look an the bridge,
all straighforward jobs.
concur, FWIWConsidering the distance between the pickguard and the side the guitar side, the waist heigth relative to the soundhole and the general shape, I'd rather say it is an LG-2.
