Guten Tag Marin,
a warm welcome from Germany (Europe neighbourhood...) You will find this a wonderful place to share information and even have a laugh from time to time
I love Tom's PS so here is mine:
PS: MvR fan here who also shares and welcomes info on other German WW1 aviators
@ Tom: I bow in deep respect to WV, undoubtedly one of the best pilots ever and a wonderful friend to MvR
