For those who may be interested there is a website which offers a cd-rom "book" which contains 185 construction photos of a Dr.1 replica. How many of the photos are of original design as opposed to a replica which may or may not be accurate is unknown to me.
The page also offers 200 contruction drawings (full size) for sale, 60 of which can be viewed on-line as samples. A few of the on-line images of larger "pieces", such as the wings, ailerons, etc. are not of very clear. The images of small haedware, ranging from small pins and connectors to control column, floorboard, rudderbar etc. are quite clear and useful.
The website is:

Also there is an excellent close up photo of the Le Rhone engine available on the Old Rhinebeck Aerodrome website:

Old Rhinebeck Aerodrome is well worth a visit, and if it is a practical trip for you to make I highly recommend it.
Definitly visit the website!
