Thank you all for the kind words. Started this project as an effort to sort out my sourcematerial. All drawings are so called public domain, most of the drawings come from the US National Archives. The drawings that are offered as free and legal download change once or twice a year.....
The drawings themselves should be taken for what they are,
I noticed the Webarchive search engine is a bit hard to use, as there is no special section for these types of drawings (yet). I've attached a zipped spreadsheet I made for personal use to keep track of the progress I've made so far. There is one column with direct links to the files on the Webarchive.
This is the
general index page for my uploads to the Webarchive
