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.
