It's a Mcdermott, the wood is correct, the pin & insert are correct for that model of cue, and the chamfer at the butt-end is correct.
The bumper might not look right, but that could have been changed at anytime.
IMO, it'd be more trouble than its worth to try to fake this - find a cue or blank with the correct wood, get a pin and insert correct to a McDermott M11B, match the the chamfer on the butt-end ...DO ALL THAT just to make a $50 or $60 bucks and risk getting negative feedback as an eBay seller
..and the kicker, if you look at the listing now there's a picture of the logo.
