Potential buyers could include private-equity firms and defense contractors including Raytheon Company, Honeywell International and General Dynamics Corporation, Bloomberg reported, citing one of the sources.

The 87-year-old company is working with financial advisers as it looks for a buyer, Bloomberg cited the sources as saying.

The sale process has been going on for several months, though a deal isn't on the immediate horizon, one of the sources told Bloomberg.
