the information on the M47's came from the Nato order of battle 1989 mod 8 that is on several websites - its been cited here in several threads
For Italy 1989 (which is basically the V1 situation)
Total tanks in inventory:
200 Leopard 1A1, 720 Leopard 1A2, 300 M60A1, 400+ M47;
2 Armoured Battalion with 34 M47 and one with 16 (they kept the 5-tanks platoons) for a total of 84; other in Carabinieri Mobile Battalions and as many as 300 in storage.
In the US section there is the following note
Tanks: 2374 M1 Abrams, 894 IPM1, 2100+ M1A1 (deliveries ongoing), 5328 M60A3, 2659 M60A1, as many as 1800 M48A5 , 1334 M551 Sheridan, 630 M47s (according to CFE records – appears to reflect fact that Italian vehicles used for decades were leased or temporary transfers that returned to US control when taken out of service)
Thus it appears that the M47 tanks in storage in Italy were leased/transfer tanks per the CFE records

The United States will destroy 640 M-47 tanks - they’re almost a half- century old - but has yet to choose a contractor, said Capt. Debra Pressley of the U.S. European command in Stuttgart.
