WOW!!! That guy is impressive!
This guy went way past good a long time back it seems. That is pure God given talent being used to it's fullest. I believe we all have at least one gift. Trick is to find it and then use it-this Gent has IMHO.That is what a good conservator can do.
Look closely on the back side pic and you can see some cross grain marks. BARELY but they are there. He made a patch and fit it in. Unbelievable talent.That looks fantastic. Did he patch it or did he make another whole grip for that side? On the back side I cannot see any difference in the graining of the wood. You got your money,s worth and then some.
