Sometime, we get requests to share for free technical information to repair, restore or rebuild aircraft.
Here is a good example of the how much cost the preservation and knowledge.
You can buy 200 drawings about the Sopwith Camel and 350 drawings about the Sopwith Pup for 179 Australian Dollars.
You can imagine this is expensive but this nothing if you count the time needed to find, finely scans, restore in some case and (the more consuming) index so much rare documents.
Last but not least take in account the investment in hardware (PC, scanners, DVDwriter, software) and expertise (how to handle such document, check the quality of the scans, store them for the new generations).
Some of us did it for Renard documents and I think to have a realistic figure of how much hours were needed is impossibble.
To have purchased technical manuals from this source ans others, I can guarantee I appreciate the time, dedication ... and the costs to preserve and share some rare aeronautical stuff when I got the documents I order.
So maybe next time, we ask someone of our contacts, everything for free, let's think about how much of his time, his money and his energy he needed to share with us.
170 Dollars is maybe not so much for motivated persons and a very small participation to the preservation of Aviation Heritage..
many happy landings
