Recently, I was approached by a hobby maker who is having problems with a violin they are making. It is clear to me, that something is quite wrong with the Strad posters they have been using as a reference.
I think we all know, that at times, there were some fairly glaring errors with these, as they went to print. Unfortunately, what might be clear to experienced makers, is not so for amateurs.
I wondered if people might list any errors they have come across, which could help others from wasting their wood.
