Lockheed L.12

The Lockheed 12 (L.12) followed the L.10 Electra of 1934, as a scaled down version for use in feeder services to and from smaller markets. Known as the Electra Junior, the type first flew on 27 June 1936, and sold almost as well as the L.10. 130 were built, mostly delivered to airlines. A small number of military versions were also built as the C-40 (UC-40), JO-1, JO-2 and XJO-3.
