The assembly measures 19" x 7" x 8.75" and consists of nine meters (one missing) relative to the "Gimbal Motor Current," with meters for yaw and pitch, "SM Bus Volt," and "Engine Propellant Valves," with part number to lower right corner: "G17-852041 Assy." Backside retains the original metal parts label, "Ten Meter Module Assy., Part No. G16-820175, Serial YAE-6974, Spec MA0201-0214, Contr NAS 9-105, US, MFR 03953," with stamped numbers below: "G17-85204" and "YAB-6974." The tops of five meters bear their Hickok Electrical Instruments parts labels, which read: "Item Name Ammeter, Edgewise, DC…Contract No. NAS-9-150…Manufacturer's Part No. 820-250." Below each meter is a "NAA CAL/CERT" plate, with several tagged as "Not Calibrated." In very good condition, with wear and staining to plastic face cover, which has started to peel at corners.
