as far as I can tell I think it is, he says 73, I found a serial number site that would placed it as produced in 72 but maybe he's off by a year or it was produced in late 72 and went out the door.
also from what I can find the placement of the thumb rest is the old fashioned way, below the strings, which it looks like they moved in the 74.
there is definitely a crack in the body but I'm assuming that is fine if repaired...my friend who knows a lot about that stuff says the only bad thing is he stripped the finish off the neck which apparently feels great at first but gets tacky as it gets dirty, but honestly I could have that refinished and still be way less than anything comparable
