I decided to start new threads on WW2 aircraft and engine manufacturers in house publications. They contain a wealth of data on what was going on at the time, including designs that never progressed off the drawing board.
Because they were a morale raising publication they naturally contain a strong bias towards the manufacturers goods and their own country. They also cover what faults were fixed in the products and a wealth of other material
I will provide links to sites I have found and I will update it as I find more and if anyone can provide links, or scans of other in house and Field Service publications for the other engine manufacturers such as Bristol, Packard, Pratt, Rolls, Wright, etc it will make this thread a good source of data and interesting "what if's"
Where practical I will also upload the magazines themselves so that if the original site dies or changes the path to the file the forum copy is still available.
Engines wise I am starting with:
..... AllisoNews, twice monthly staff newspaper from Allison
..... Tail Spins, Monthly magazine for Allison Field service reps
I will edit this page to link to the Airframe manufacturers pubs once started with Convair, Curtiss and Ryan.
So - first the site for the above Allison publications is
Allison Transmission or
Allison Transmission
I will upload the Tail spins first in the next few posts and AllisoNews in a separate post or two after that.
Happy reading
