Thank you for those quotes, Bernd. I especially like the one about the use of patterns, which is something I also noticed and found very VM-like.
Regarding the possibilities of copies, they must have existed because these Renaissance men needed to make a name for themselves. Marco referred me to this work from 1972: You are not allowed to view links. Register or Login to view.
On p.16, it is suggested that a copy must have been given to the emperor Sigismund in 1433.
I guess one could object that these materials would only be available in the upper echelons of society. But to me this feels like information rather than a problem
