C-B Tool Products
C-B Tool is an AWE facility for 1944 so workers are eligible to file Part B claims.
For a six month period in 1944, C-B Tool Products Company had a subcontract with the University of Chicago to provide personnel, facilities, and equipment to produce special machining of parts for special equipment, tools, jigs, and fixtures to the Met Lab from materials provided by the University of Chicago. It is unclear whether the company handled radioactive materials.
