That is a pretty astonishing bit of restoration work... how did you strip the old model down? I think I've got a few candidates for similar treatment!
I've loved Hans Illner's '109 since the the first time I saw photos of those lips...! A bit different from a "sharksmouth"! I can't see what canopy you've got in the pics, but my references show an early style "un-armoured" one. If you're really feeling ambitious "Gretel" may have been painted in yellow... hard to tell.
Hopefully, you've seen Holdfast's post suggesting an annual BoB campaign...
All the best
Rowan
