Just read that There are no known original DR.1 Fokker triplanes in existence.
Lots of interesting info thanks Stuntie
Sadly no.
And whilst we have some originals preserved, such as the Fokker E type in the London Science museum, the captured DR.1 and DVII etc. were not saved.
Sadly Allied Bombing destroyed some German Museum ones, such as one in Dresden, and another place that I can't recall right now.
One of which was I believe one of Ricthofens DR.1's.
