Fis h s r Bony No r w o o d Div is io n Ge n e r h i, Mo t o r s Go r p o r h t io n j\ORWOOia, Oh io June 18, 1935* Dr. R. A. Keboe, Kettering Laboratory of Applied Physiology Eden & Bethesda Ave. Cincinnati, Ohio. Dear Doctor* The enclosed filter is taken from a respirator which the employee says he has used for one week. The operation consists in discing down lead seams, the disc containing circulating water, which we believe cuts down the lead hazard* Wq would appreciate it if you would determine the amount of lead present and advise us. We will let you know later how many hours this filter has been used. Kindly send your bill for this service to Fisher Body--Norwood. RDM. EM N9847
