The LeO 45-01 seen late in 1937 after the introduction of projecting oil coolant radiators and redesigned and lowered vertical tail surfaces.
This photograph of three LeO 451s of GB 1/25 fitted with the ultimate vertical tail surfaces shows clearly the outstandingly graceful contours of this medium bomber.
LeO 455 No 3 (ex-LeO 451 No 602) photographed at Villacoublay on 3 December 1946. This aircraft was originally flown on 22 October 1945 in LeO 455 form and assigned to SNECMA as a GR 14R test-bed.
Leo 451 No 359 of Escadrille 6B experimentally modified for use in the mine-sweeping role with dural frame energised by an auxiliary motor. Additional bracing struts were introduced subsequent to the photograph being taken.

LeO 455 Ph No 3 (ex-LeO 451 No 421) operated for mapping and survey tasks by the Institut Geographique National and photographed at Nice in July 1952. Note the larger elliptical vertical tail surfaces that were standardised for the five LeO 455s acquired by the Institut.

Leo 451 No 359 of Escadrille 6B experimentally modified for use in the mine-sweeping role with dural frame energised by an auxiliary motor. Additional bracing struts were introduced subsequent, and these are illustrated by the general arrangement drawing.
