You are bidding on a collection of over 100 scanned manuals on aircraft piston engines from the 20’s through the 60’s, available by DOWNLOAD ONLY. All the manuals have been indexed using OCR. There is also an overall combined index across all the manuals in this collection. To limit the subject a bit, there are only four manufacturers represented here – Rolls-Royce and Allison for the V-12 liquid-cooled engines used in fighters and some English bombers, and air-cooled engines from Pratt & Whitney and Wright Aeronautical. Manuals have been scanned at between 300 and 600 lpi. Color pages have been scanned in full color. Wide fold-out pages were scanned on a large-format scanner. ALL pages have been hand-edited.

These include the following engines:

Allison V-1710 (6 manuals)
Rolls-Royce Merlin V-1650 (8 manuals)
Pratt&Whitney R-1340 (1 manual)
Pratt&Whitney R-1830 (12 manuals)
Pratt&Whitney R-2000 (1 manual)
Pratt&Whitney R-2800 (9 manuals)
Pratt&Whitney R-4350 (1 manual)
Pratt&Whitney Other (13 manuals)
Wright R-1820 (3 manuals)
