These Consolidated Vultee specs were a nightmare. Every page has required a LOT of work. As a guess they have been printed from microfilm, with something in the printing freaking out the scanner, and then cut to size (yep no two the same size.) Despite several scanning changes the scanner has picked up some sort of watermark in the paper in most scans. This same watermark is usually not visible on the original. The paper itself is probably double the weight of regular paper and has an uneven blue tinge.
My apologies but this is the best I could get them without wasting any more time.
