The LGL-32 was the only Gourdou-Leseurre fighter to be built in really substantial quantities.

The LGL-321 was a more powerful version of the LGL-32, the sole example being a re-engined pre-series aircraft.

The LGL-33 was a Lorraine-Dietrich-powered derivative of the basic design.

The first (on photo) and second LGL-341 prototypes differed essentially in engine cooling arrangements. An insufficient performance advance over the LGL-32 militated against series production.

The GL-410 and the GL-450 (on photo) were based on the LGL-32 and differed from each other in having supercharged and unsupercharged engines respectively. The former had a wing of trapezoidal shape.
