I want to know the answer to the following question:
Which company manufactured cameras in Ann Arbor from 1936 to 1960's?
All the background I'm provided with is that "High tech companies have located in the area since the 1930s, when International Radio Corporation introduced the first mass-produced AC/DC radio (the Kadette, in 1931) as well as the first pocket radio (the Kadette Jr., in 1933).". Is that enough to answer the question?
Answer: no
