[cctalk] Identification of Core Memory Unit

Requesting assistance in identifying a ferrite core memory unit. My father was an RCA, then Univac, field engineer on-site at Connecticut General Life Insurance in Bloomfield, CT, in the late ’60s and ’70s, and brought this home. Large cores on a coarse grid, hand-laced harnesses, U.S. Components MI-75 connectors, stenciled position numbers 876 and 825, frame stamped “Ser. 175.” Mounted under plexiglass. Suspect RCA 301 or 3301 or early Univac. Does anyone recognize it or know what CG ran in that era? Photos attached. Thanks, Carlton
