I don't know. I'm not very knowledgeable about Hannover finishes. I think there is some controversy regarding this particular aircraft. If I remember correctly, It was originally thought this machine was downed by Rickenbacker (and labeled as such on the fuselage), when it was actually brought down by ground fire. The Hannover Rickenbacker shot down was a different aircraft. If I have this wrong, I hope someone will provide the correct information.
