MvR did not use any symbols on any of the Dr.I's he flew.
He was know to have flown Fokker Dr.I 102/07, 114/17, 127/17, 152/17, 161/17, 477/17 and 425/17 the one he was shot down in.
You can find a link to some color illustration in the Dr.I profile section for these and other Dr.I's to see for your self. You can also see the photos of these machines in the photo section to compare.
