Coming clean on a Mantle MMF

Gentlemen, I have to come clean and say that a recent Mantle MMF sold on ebay was one I had. Here it is:

A friend of mine sold it for me. I had picked it up, along with an old Wilson and a Nokona, in order to get the Nokona glove. I worked on it to clean it up and relaced it, using new Tanner's lace in the pocket and fingers and vintage Nokona lace (in very good condition) on the palm and other areas. Just thought I'd fix it up some before selling it. Wasn't wanting to make a killing off of it, just didn't need it so I thought I'd pitch it out there. I tried to list all the faults so as not to mislead anyone. Better to be over critical than to sell a "pig in a poke".
Well, the guy who bought it is now giving my friend a hard time, saying it wasn't completely relaced, evidently saying the vent holes on the back were supposed to be laced. He wants my fried to halve the cost of relacing with him or he'll post negative feedback.
I've read here that those are vent holes on these MMF gloves. We sent him pictures of other MMFs showing the same holes. There is an extra hole in the thumb area that, quite frankly, has me puzzled. I can't remember what it was but you can see it on the photo. I tend to think it was a vent hole as well but other models don't show it.
Any suggestions on how to resolve this? I personally think the guy's trying to get my friend to cut the cost after he bought it. They're still trying to resolve it.
