And most folk would have very carefully placed it on a towel/blanket/etc. - wood and bricks/concrete just don't play well together. Guess it's all in how you're in the habit of treating your gear.
Would suggest a picture of the other side too. Perhaps it's my monitor but from the picture you posted, looks like a nick on the bottom of the grip and noticeable wear around the butt - not really a problem, but if actually there and not a photo artifact, not 97% either.
Is it a left hand stock, the tape measure placement makes it tough to tell?. Either way, doesn't seem to be an outrageous price for the stock, good luck.
