[g-1reaper]

Please remember, the type designation "G-1B" was an afterthought which was first used by well known Dutch author Bart van der Klaauw.
Fokker did not use this type designation.
The correct type name is Fokker G.I (G dot Roman I) Wasp. This is the two seater variant, while the three seater variant with Bristol Mercury engines was simply known as Fokker G.I (G dot Roman 1) Mercury.

btw. I could not use a dot in my username so my name should be G.Ireaper ;-)
