With all respect!
The picture shows a German Army M48A2GA2.
Starting in 1977 the M48A2 equipped German armor battalions were ordered to sent lots of 5 ea M48A2 to FFG (Flensburger Fahrzeugbau Gesellschaft) at Flensburg for depot maintenance. The tanks were like new AFV. From Flensburg the tanks were send via rail to the Wegmann factory at Kassel. FFG had already removed the mantlet, the M1 TC cupola with .50 cal M2 HB and the M41 90 MM gun. At Wegmann the M48A2 were equipped with a new designed mantlet, the L7 105 MM gun und a Leopard 1 like TC cupola with a MG 3. These tanks got the nomenclature M48A2GA2. As far as I know, the US Army armor battalions in USAREUR, starting in the mid-1960-ties were equipped only with M60 and M60A1 MBTs
