Code Designator Slide Chart - FELSENTHAL FAA-141A

Description
This slide chart is designed to assist in coding United States Air Force forms for inventory control. The envelope is of clear plastic printed in blue, with a white plastic card that slides crosswise. The sliding card has columns for eight Air Force forms (forms number 158A&B, 158C&D, 813, 814, 815, 158-7, 366J&K, and 366L&M). The numbers in each column indicate the place on the form on which the data is to be entered. For example, in all eight forms spaces 1through15 are for the stock number and spaces 31through 34 are for the organization number. The first 56 spaces are described on the front of the sliding card. The remainder (up to 80) are on the back.
It is possible that the forms described are 80-column punch cards, such as those made by IBM for use with electronic data processing equipment.
A mark on the front of the envelope reads: Code Designator (/) Slide Chart. A mark on the back of the envelope reads: Felsenthal Instruments Co.1963 (/) Chicago 31, Illinois (/) MFR’s PT.NO. FAA-141-A.
