I have permission to share the following photos of the very first swimming pool in Oberursel, which belonged to the Motor Pool.
1929: pool party or Sommerfest (summer fest)

Summer fest 1929
On 30 March 1945, U.S. troops occupied the town of Oberursel and the Motorenfabrik (Motor Pool). The Motor Pool remained in U.S. American hands until 1956/1957.

Change of hands: The Americans returned the Motor Pool back to the Germans in 1956/1957
The Motor Pool also had its own fire department. The next three photos show a fire drill held in 1969.

For more about the history of the Motor Pool, have a look at the book at 125 years of Motor Pool history , a post I had written about the author Helmut Hujer, and his work.
