I recently went to the Musée royal de l’armée et de l’histoire militaire or Royal Museum of the Armed Forces and Military History in Brussels.
The North American Aviation T-6 Texan is an American single-engined advanced trainer aircraft, which was used to train pilots.
The AT-6D is a later version and was used by the Belgian Air Force between 1946 and 1961. This AT-6D was on display at the museum.
