Title: Stinson L-1 Vigilant

The L-1 was originally designated the O-49  and ordered into production in 1940 by the USAAF as an air observation aircraft. Redesignated L-1 in 1942, the aircraft was used extensively in both the European and pacific theatres, though later superseded by the more lightweight L-4 Grasshopper aircraft. Examples were used by the British as the “Vigilant” under the WW2 lend-lease program. The aircraft was modified for both ambulance and floatplane roles.

This title contains the USAAF pilot flight manual and the Erection and Maintenance Manual for the L-1 series.  The files have been scanned from the original flight manuals and retain any colour pages.
