Sure seems to have a pretty defined turn line for a new gun! Might be the picture but the brush lines look to cut through the ampersand on the left side. My newest (686 from 2013) the laser etching for the ampersand was obviously done after the brush finish.
To me it looks like somebody bought a new 629, abused or damaged it, did a refinish and returned it to Grabagun who put it back in stock and resold it.
Keep us informed what both say about this.
