Pair of Saturn V Exploding Bridge Wire (EBW) Pulse Sensors, measuring 4.75 x 2.25 x 1.75, both identified with NASA George C. Marshall Space Flight Center tags reading, "EBW Pulse Sensor, Assy No. 40M02852, Contr No. NAS-w-410," with serial numbers of "358" and "378." In overall very good to fine condition. These were utilized for ground based checkout of the firing circuits used to trigger the Saturn propellant dispersion system. The pulse sensor was temporarily installed prior to launch and detected normal operation of the EBW firing unit discharge circuits.
