I would think that the current publishers would
still have those drawings available in their plans service at 1/72 and probably
at 1/24. I think the publisher is now NEXIS or NEXUS and details of how
to get such drawings are usually mentioned somewhere in each magazine.
Sorry I cannot be more specific but I have not purchased an Aeromodeler mag for
many years.
The drawing may also have been published in one of their special collection
books but from memory it is not in Vols 1,2 & 3 of WW1 Aircraft.
Hope that helps
