"Orgeneral Tural Kariyeri" (Major General Tural [armored personnel] carrier) was based on the converted chassis of M24 Chaffee light tank, which were transferred from US in numbers in early 1960's, after Turkey joined NATO.
It was designed as a reconnaissance and light troop transport vehicle.
Technical specifications of the Tural APC are as follows:
Crew: 12
Weight: 18t
Weapons: 1 x 57mm gun, 2 x 7.62 machine guns
Range: 100 miles
Speed: 58 km/h
A small number of vehicles were converted in mid 1960's and all retired in 1971.
By the way, Major General Cemal Tural was the CinC of Turkish Armed Forces between 1966-1969. He was also a pioneer of armored warfare. If memory serves right the Tural APC project was started by his directive, either at the last stages of his post as Land Forces Commaner or early CinC.
One example of the Tural APC is (must be) present at Etimesgut Tank Museum, Ankara (the one in the very first photo, the of the thread)
Speculation: Maj. Gen Tural retired in 1969. He was an important actor in the turmoils that included many fractions and junta attempts within army. There were allegations that he even attempted a coup d'etat. Given that, the date of the cancellation of the project right after his retirement suggests that the reason of the retirement of Tural APC's was political, rather than technical / technological.
