Set of 39 U.S. Navy recognition training slides Spanning 1945-56 and the early Cold War with the Soviet Union. Slides Sandwiched In Glass.

Slides like these were developed during World War II as a training tool, for top-side battle-station personnel on board ship and for all aircraft personnel, by the US Navy. In 1942 a Recognition School was established by the Navy at Ohio State University where the method of identification was developed. In 1943 the school was taken over by the US Navy. The importance of training in visual recognition of ships and aircraft became even more evident during World War II. Mistakes resulting in costly errors and loss of life led to an increased emphasis on recognition as a vital skill.

In other words, you couldn’t mess up your Japanese zeros with American heroes, or there would be a tragic mess.

These slides cover the Cold War period from 1945 through 1956 with the majority covering the fifties and Soviet (USSR) aircraft. American and British aircraft are also represented, but to a lesser extent.

The slides themselves appear to be standard 35mm black and white, but they are encased in thin sheets of

glass (I noticed a that one slide may have a crack in one side of its glass. I have NOT checked for any defects.). They could use a cleaning, but I will let the seller do that.

More on condition: Condition is subjective. I GRADE NOTHING. The buyer must take the risk that these slides meet his or her needs and standards. I mentioned the dirt and cracked glass. There may be other condition issues that I do not know about because I have not checked any slides in a projector. Please look closely, and ask questions. Know that if an obvious defect came to my attention from my casual examination of these slides I will mention it here.
