This series consists of one manilla folder containing a supplementary subject classification list to enable otherwise doubtful submissions to be indexed. Ordinarily the Army Inventions Directorate (AID) used the subject classification as used by the Patents Office but due to the complex nature of some of the submissions the AID received it was necessary to produce this supplement. The series relates to MP1164/7.
