You are bidding on a DVD-ROM with high-quality PDF scans of all 26 volumes of Molloy's Aeroplane Maintenance and Operation Series. These were issued in Great Britain over the 30's and 40's. This is over 2000 pages of vintage aircraft information, mostly from British manufacturers.
As I have edited every page of every manual to remove blemishes and scanning problems, the images in these files  differ from the original manuals. My changes are all copyright 2004-2022. Permission is given for personal, educational, and research use only.

Molloy has given us a full course in the operation and maintenance of airplanes that were just on the cusp of moving from wood-and-canvas construction to metal-frame aircraft. This was an era of very hand-on maintenance. Anyone that could fix a car could repair, or even build, an airplane. There are also a handful of "extra" volumes of related information from this era.
