Here's a pic of an early L-4, probably an A model. It has the black prop, wind generator, and early greenhouse. Also notable is the plain May 1942-June 1943 national insignia with no bars or red spot, the lack of edge scalloping, and the buzz number applied to the fuselage forward of the national insignia. I make it to be 336384. Wish the pic were larger. Photo credited to Stan Piet.
