P-38's used as "Tojan Horses"??

Captured P-38's used as "Tojan Horses"?
In at least 2 seperate accounts I've come across-captrued P-38's aircraft were used as "Trojan Horses":
1) A Colonel Tondi used a P-38 to shoot down a B-17 on
11 AUgust 1943.
2) A Lt. Guido Rossi used a P-38 to shoot down a B-17 on
4 June 1943. (Rossi captured 31 August 1943)
A) Were these the only cases of B-17's shot down by "Trojan
Horses"?
B) What was the Seriel Number/FS/FG of the P-38's used by
Tondi and Rossi?
