Found this to explain it. They swapped out the nose to making more streamlined for testing against the P-80
"Photo-reconnaissance variant, named 'Connie the Sharp Article' and then 'Pick II'. Aircraft of Lt Roy W. Brown. Shipped to the USA aboard the HMS Reaper. Ferried from Newark to Pittsburgh and then to Freeman Field on 19 August 1945 by Col Harold Watson. Became 'FE-4012'. This aircraft had a fighter nose substituted for the bulged reconnaissance version after arrival in the US. It is now at the Planes of Fame Museum at Chino in California wearing the incorrect W Nr 111617.
This aircraft was surrendered to US Forces at Lechfeld and was named Connie the Sharp Article, with the number '444'. It was later re-named Pick Il by Watson's Whizzers. It came to the USA aboard HMS Reaper and was flown from Newark to Freeman Field IV Col Watson on 19th August 1945. While at Freeman Field it was reconditioned and given an overall smooth finish for performance comparison with the Lockheed P-80. This process almost certainly involved the removal of its photo-reconnaissance-type nose and its replacement by a fighter-type nose without camera bulges. On about 17th May 1946 Col Watson flew the aircraft to Patterson Field for the start of this series of trials. It was flown at Patterson and Wright Fields on test work for 4 hours and 40 minutes (8 flights), being flyable at Wright Field in August 1946. Flight trials were discontinued after four engine changes were required during the course of the tests, culminating in two single-engine landings.
It was later handed over to the Hughes Aircraft Company. Howard Hughes proposed to enter the aircraft in air races in competition with USAF P-80s but this was officially frowned upon and the proposal was cancelled. The '262 had, in the meantime, been shipped to Hughes at Culver City, Ca, and was assembled and the engines run, but it was not flown by the Hughes company.
The '262 was disposed of to the Glendale Aeronautical School for use as an instructional airframe, until, after some years it was acquired by Edward T. Maloney for his Air Museum at Ontario, California. FE-4012 is currently with the Museum at Chino Airfield, California, marked as W Nr 111617, which is incorrect, the color scheme being copied from the original 111617, which was scrapped on a dump near Munich at the end of the war."
The last info is prior to Flying Heritage doing their restoration.
