FBA 17
The FBA 17 was a training flying boat produced in France in the 1920s. Similar in general layout to the aircraft that FBA had produced during World War I, the Type 17 was a conventional two-bay biplane with unequal-span, unstaggered wings and side-by-side open cockpits. The pusher engine was mounted on struts in the interplane gap. Apart from their use by the French Navy, a small number were sold to the Polish Navy, the Brazilian Air Force, and civil operators as well. Some versions were built as amphibians, and others had fittings to allow them to be catapulted from warships.
In 1931, the US Coast Guard purchased an example for evaluation, and being pleased with the design, arranged for the type to be built under licence by the Viking Flying Boat Company in New Haven, Connecticut. Six aircraft were eventually produced and served with the Coast Guard under the designation OO until the outbreak of World War II.

FBA 19
The FBA 19 was a flying boat bomber developed in France in 1924 by Franco-British Aviation. Similar in configuration to FBA's wartime designs, it was a conventional biplane flying boat with open cockpits for the three crewmembers. Unlike the firm's earlier designs, however, the engine was mounted tractor-fashion in a streamlined nacelle mounted in the interplane gap. The prototype set a world altitude record for its class with a 500 kg payload, but despite this performance, the French Navy did not order it, either in its original form or when it was offered as an amphibian. Another version was built as a commercial transport, but only one machine was sold (to Air Union).

General characteristics
Model (art)
An art model is a model who poses for any visual artist as part of the creative process. The most common types of art works which use models are figure drawing, figure painting, sculpture and photography, but almost any medium may be used.
Art models are often paid professionals who pose or provide the human figure in a work of art. Though professional, art models are usually anonymous and unacknowledged subjects of the work. Models are most frequently employed for art classes or by informal groups of experienced artists that gather to share the expense of a model. Models are also employed privately by professional artists. Although commercial motives dominate over aesthetics in illustration, its artwork commonly employs models. For example, Norman Rockwell used his friends and neighbors as models for both his commercial and fine art work. An individual who is having their own portrait painted or sculpted is usually called a "sitter" rather than a model, since they are paying to have the work done rather than being paid to pose.
Mimicry
In evolutionary biology, mimicry is a similarity of one species to another that protects one or both. In the case of prey species, it is a class of antipredator adaptation. This similarity can be in appearance, behaviour, sound or scent. Mimics occur in the same areas as their models.
Mimicry occurs when a group of organisms, the mimics, evolve to share perceived characteristics with another group, the models. The evolution is driven by the selective action of a signal-receiver or dupe. Birds, for example, use sight to identify palatable insects (the mimics), whilst avoiding the noxious models.
The model is usually another species, except in cases of automimicry. The deceived signal-receiver is typically another organism, such as the common predator of two species. As an interaction, mimicry is in most cases advantageous to the mimic and harmful to the receiver, but may increase, reduce or have no effect on the fitness of the model depending on the situation. The model may be hard to identify: for example, eye spots may not resemble any specific organism's eyes, and camouflage often cannot be attributed to a particular model.
