Carr to Route List, dated 11/29/73, Raw Material Review Meeting date January 7, 1974 Copy TO J. F. Bubnis H.B. Carr M. Fields R. S. Miller W. Miringoff G.I. Rozand P.R. Scarito A. C. Siegel ^Tile As stated in the referenced memo, Purchasing advised Manufacturing to maintain a three-months' inventory of raw materials, where this would be feasible and appropriate. Prior to implementing this, Quality Con trol agreed to review raw material storage requirements for Manufactur ing, Attached is a listing of the storage requirements. Attachment. FWK/jst F.W.
