Though I am not aware many tanks getting captured by british or americans (except for Cuckoo)
Cuckoo might have been an exceptionnal case.
The only other example I know of Allies using captured equipment are:
- the British airborne troops at Pegasus Bridge turning a PaK 40 & Flak 20mm against their former owner. But they hold on it for a mere day at best.
- by the end of 1944, early 1945, due to lack on ammunitions, the US Army organized 2 or 3 three batteries of artillery with captured 88mm guns.
- French FFI (= Résistance) in 1944-1945 using captured German tanks against the German pockets still holding along the Atlantic coast (see Escadron Besnier, which was composed of 1x Tiger I, 1x Königstiger, 1x Panther, 11x Panzer IV, 1x Panzerwerfer 42 & several half-tracks).
- the US 83rd Infantry Division was dubbed "Rag tag Circus" in Germany in 1945, for its commander had orderer to press into service any serviceable German vehicle along the way, in order to improve the division's firepower & mobility in its ride East. They are known to have commandeered this way a StuG, several half-tracks, and even a Messerschmidt fighter (and found someone in the division able to fly it)! But, unlike Cuckoo, those were used has long as they were running, then ditched.
- 129th Ordnance Battailon in the Ardennes even had restored a Königstiger!
The only case of official and major use of captured enemy equipment by the Allies was, AFAIK, in the Libyan desert. There, both side used A LOT of enemy equipment.
The whole 9th Austrialan Division was equiped with Italian trucks and guns captured from the Italians, and even had formed an armored company with first French R-35 or H-35 captured from Vichy troops in Lebanon, then with Italian M11 & M13.
Still in the desert, a Free Polish armored unit was formed entirely of captured Panzer III:
Any Allied unit in the desert capturing an Italian Breda 20mm gun in working order would try to bolt it on a vehicle to reuse it. LRDG were especially fond of it:
