Avialogs is not only about flight manuals and technical documents, we have a large collection of aviation books, blueprints and photographic documents. When I started this project five years ago, I did not expect to discover a few treasures, some of them found by chance, other by research.
1929, despite several flights since 1919, crossing the Atlantic by aircraft is still a dangerous endeavour. During the spring and summer of 1927, 40 pilots attempted various long-distance over-ocean flights, leading to 21 deaths during the attempts.
Early aviation engines are a fabulous topic to explore. From rotary, to early liquid cooled inline configurations, these designs were defining technologies and powered progresses in flight.
More and more documents are added to the Avialogs library and on the site, thanks to users who shared their collection. Not all documents are yet scanned, mainly as original are extremely fragile and I am looking for solutions how to scan them without damage.
If you collect aviation related documents, you are probably familiar with the many different WWII publications: American military technical manuals, US Air force technical orders and pilots notes published in England.
Whilst copies and reproductions for these documents are commonplace, the pilot's notes pose a real problem: the quality and number of copies is probably even greater than the original publications !
Let's try to make sense of all this! Two principal publishers have reproduced the pilot's notes.
The most important of these is Crecy Publishing, Air Data Publications, who produced over fifty volumes between the 1970's and start of 2000. Actually from 1967 to be precise. These manuals are easy to identify as the front cover has "Crown Copyright - Reproduced by permission of Her Majesty's Stationery Office" or "Reproduced by permission of the United States Government" printed on it. It is worth noting that often these manuals only have the original publishing date indicated which can cause confusion. Often the mediocre quality paper used in the 1970's has prematurely aged and this yellowing can make it look like an original.
Copy from Air Data Publications and original
Authentic manuals often have updates stuck onto the original pages making them up to twice as thick and visibly modified. For reproductions, such updates are usually incorporated into the work as though part of the actual work. Another giveaway is where the cockpit views are folded but you can see where the original folds were meant to be by the darker lines.
The second group of reproductions are from Sapphire Productions. These reproductions often include handwritten notes appearing as printed into the document and they have a cover slightly different to the original work (showing the Air Publication reference and the title with no other information). Paper is different too from original.
The attached photographs will enable you to spot the differences...

Ebay poses an interesting problem. You can find everything there, real and fakes in abundance, sold often as originals and at staggering prices more often than not. Try a search with keywords of "Original" & "Pilot's Notes" to see the scale of the phenomenon.
Whilst some of the sellers are certainly dishonest, others really don't know any better what they are selling. Sometimes this enables one to find a great deal but in most cases just serves to confuse beginner buyers.
Good Luck collecting!

Avialogs exists since 4 years now. We have built the largest online aviation library and now we move to the next phase of our goals: To preserve our aviation heritage. We have done the acquisition of a Stinson 10a, a light aircraft used for air patrol during the second world war. Our goal is to restore her to airworthy condition.
The aircraft require a complete restoration. This first phase of financing is targeting to raise enough money to restore the fuselage.
Our Stinson is a model 10a, built in Consolidated factory in April 1941, serial 7816, initially registered NC31567.
Two man crews of the Civil Air Corps flew the Voyagers along the eastern U.S. coast. They patrolled for German U-boats and ran search and rescue missions for survivors of allied merchant ships torpedoed by the Nazi submarines.
CAP's coastal patrol flew 24 million miles, found 173 U-boats, attacked 57 of them with 83 bombs and depth charges, hit 10 and sank two. The Civil Air Patrol lost 26 men and 90 airplanes.
Referred to as "little yellow bees" by U-boat commanders, the Voyagers originally flew unarmed. But they were soon authorized to carry a single 100-pound bomb after a U-boat that was spotted by a CAP crew - and stuck on a sandbar - got away before the U.S. military arrived.
The project is to restore the aircraft to air worthy condition within the next 4 years. This first round of financing targets the fuselage restoration.
Fuselage must be sandblasted, a few tubes replaced (corrosion) and primed.
You money will help the project to progress more fast.
Thank you for your support.
