The Pratt & Whitney R-1830 Twin Wasp radial engine was installed in such well known planes as the Consolidated B-24 Liberator bomber, the Douglas DC-3 transporter, and the Grunman F4F Wildcat fighter plane. 173,618 were made in total. The wreckage on display was excavated at Szigetszentmiklós in 2008. It is thought to have been one of the engines of First Lieutenant Charles W. Bauman's B-24. The plane was shot down by anti-aircraft artillery on 13 April 1944 when the 451stBomber Squadron was attacking the Duna Aircraft Factory.
