Looks pretty much like a gen-u-wine mid-seventies (not their best period!) Gbsn ES-175 to me. What makes you suspicious?
It has had a headstock repair - has to be a real Gibson. I agree with the above poster - what about this guitar looks inky to you.
Michael's Music is a reputable store that has been around a long time. Also, the sunburst is ugly enough to look authentic '70s :-}.
Do you know what years the ES-175s had those knobs with the gold tops? I had one like this years ago, also with the squiggle tailpiece, and never knew what year it was. Mine had a wood bridge, though. Great guitar, wish I had that one back.
