FactoryRegistry lists 4,185 facilities whose primary industry classification is one of the 3 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced aeronautical, nautical, and navigational instruments, not sending or receiving radio signals (excluding engine instruments), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
