Bernd: the question about Lauber's sources is one that vexed me greatly in the past. These guys churned out manuscripts at an unprecedented rate and they copied readily from available sources, reused characters, poses etc.
It's important to keep in mind that Lauber built his workshop on the legacy of an earlier, more mysterious one in Haguenau. This probably deserves more research, as they were closer in time to the VM.
Still it's all very complex, and it's quite possible that Lauber got his hands on the sources that interest us at a later date.
