Several years ago I was visiting someone at a hospital in Elmira, NY. An elderly man who was visiting his wife in the same room mentioned that the Norden bomb sight was manufactured locally. At the time the Elmira area was filled with abandoned plants so my thought was that if the Norden bomb sight was Elmira's last claim to fame, that said a lot about the depressed economic state of the area.
But as you point out Lucas-Harold was in Indianapolis. So perhaps the man I spoke with was not even correct.
