Two Apollo space suit pressure gauges, measuring approximately 1.75˝ x 1.25˝ x 1˝, which were located on the lower arm so that astronauts could quickly verify their suit pressure. The tops of the blue housings are etched as “Class III” and engraved with matching part numbers, “A6L-104025-04,” and different serial numbers, “269” and “275.” Both gauges were manufactured by DMD for ILC Industries, Inc. In overall fine condition, with two small cracks to one window.
