I’ve recently purchased a number of blueprints from ebay, all of which will be scanned and added to the monthly catalogs. They include:
Four vintage Vought blueprints (3 of the unbuilt V-451 “Guerilla,” one of the V-447, would become the XC-142).
Boeing Model 301 Heavy Lift Helicopter.
Inboard diagram of the Convair SKATE seaplane attack jet, 36 inches wide by over 6 feet long. Spectacularly, this is the *original* hand-drawn pencil diagram on vellum.
