Found some keys, Maybe Saftey Deposit?

Could belong to the old Hughes aircraft facility or GD, but I highly doubt they are safety deposit box keys judging by the shoulders and notches. Deposit box keys usually have squared shoulders and notches. They look like they're older keys used for storefront doors or safety doors like an aircraft facility might use.

His official job was lead electrical engineer and worked on numerous military contracts for hughes/GD. He was one of the few people who designed the Maverick and a few other explodey things.

Just checked and one of the keys does say BEST right below the keyring hole.

They look like government keys. I've had almost identical ones for various old buildings and barracks that i've lived in on military installations.

That's what my mom thought they were. She remembers him having them on his car keychain when he was working in there the 1980s.
