Yeesh. I continue to successfully get rewards out to Patrons and subscribers in a timely fashion… but I also continue to fail to publicize the fact. Last day of September, the rewards for that month were sent out. The September 2021 rewards included:
Diagram: “Early X-3 cutaway:” A large format cutaway illustration of a not-quite-final Douglas X-3 configuration
CAD Diagram: the command module of the Solem “Medusa” nuclear pulse propelled spacecraft
Document: a giant 1100+ page “Data Sheets for Ordnance Type Materiel,”1962 US Army “catalog”of pretty much all their stuff. Includes an illustration (often, though not always, including a basic diagram) and data for everything from trucks to tanks to bayonets to pistols to rockets.
Patrons should have received a notification message through Patreon linking to the rewards; subscribers should have received a notification from Dropbox linking to the rewards. If you did not, let me know.
If this sort of thing is of interest, sign up either for the APR Patreon or the APR Monthly Historical Documents Program.
