Heavies Allies in Axis markings

I share with you a collection of photos, some of them extremely rare, showing Allied bombers captured by Germans, Italians and Japanese. One question, does anyone know if during the Second World War a B-29 bomber was captured and tested? To see the photos, visit the link below:

Not by the Japanese AFAIK. The Soviets however impounded several B-29’s and essentially reverse engineered the B-29 into the TU-4.
