I'm sure they didn't bomb the museum specifically, but that the museum was hit during an air raid, so there might not be any mention of it in allied reports.
But i found this:
"The aeroplane motor collection of which parts are exhibited in Cracow The largest aviation museum in the world was once situated in Berlin, which is largely unknown today. The "Deutsche Luftfahrtsammlung" (German Aviation Collection) was in Alt-Moabit Street near Lehrter Station, housing more than 120 planes, 200 engines, pictures, models, cups and many other things. When Berlin became more and more threatened with bombing raids by the allies, a plan was developed to transfer this museum. Fritz Petereit, who was born in Treptow on the Rega river, an employee at the airport's society was commissioned to plan the transfer. Due to his origins he was convinced that Pomerania was one of the safest areas in the German Reich. Thus, in June and July 1943 the museum was evacuated to a great extent and everything was shifted either by train or trucks to safe places. Petereit remembered in this context transportations to Treptow, where three or four aeroplanes were stored in the pottery Ernst Bordt of Bollenburg and in the storeroom of the Laabs Brothers carpentry in Großen Küte Street. Many aeroplane engines were kept in the dance hall of a restaurant in Darsow, between Gummishof, Levetzow and Dargislaff. Two aeroplanes were removed to Hammer, between Schonlanke and Scharnikau; further aeroplanes were likewise taken out to Schlachau, possibly to the drying places of a brickyard. Several aeroplanes were stored in Ratzebuhr, north of Schneidemühl. Finally, the Quast Guest House of Neuhofen, between Fihiene and Scharnikau, was the storing place of three or four aeroplanes. After 40 years Petereit understandably could not remember further storing places.
For at the end of the war only 24 aeroplanes of the "Deutsche Luftfahrtsammhmg" were discovered by the Poles, the question arises what has happened to the remaining ca. 100 planes. Surely many were destroyed during fights. Since the museum also housed quite modern airplanes, some of them may have been taken away by the Russian Army. It would be of great importance to know whether the reader can remember anything relating to this matter. Who possibly had noticed in the summer of 1943 something concerning the transportation of aeroplanes? Did anybody notice aeroplanes in the storerooms or dance halls of their villages?
In connection with the museum's further extension and the current negotiations between the Federal Government and the Polish Government concerning the return of cultural objects, it would be of great importance to obtain more information and perhaps to receive some pictures, too. "

Now if "Deutsche Luftfahrtsammlung" (German Aviation Collection) have been mistaken for "Deutsches Technikmuseum" ("German Technical Museum") then we are looning at another story.....and i think it WAS!
