I disagree with your assertion that the Fellowcrafts were the overseers of the work and verified the work. That is just not how medieval craft guilds worked. In the medieval guild system an Apprentice would be sent to work for a Master for several years (5-9 depending on trade) with no pay while he learned the craft from his Master. As the Apprentice progressed he would become a Journyman or Fellow of the Craft where he continued to work for His Master. The major distinctions at this level were the ability to marry and the ability to receive modest pay. Only after the Journeyman finished his "Masters Piece" would he be able to become a Master of the Craft. This new status would allow him to set up his own shop and take on his own Apprentices.
