Kennedy 520 machinist toolchest
My dad is a retired avionics tech, he knows how to fix any electronic thing in an airplane. He's had a toolbox like this as long as I can remember. He used to take in on planes when he'd fly to go fix them. Kennedy has been making them in Ohio, apparently unchanged, for like 100 years.
The toolchest has several felt-lined drawers (so the tools don't shift around), with adjustable metal dividers in the drawers. A front cover hides all the drawers and protects them when the chest is closed, otherwise it slides underneath the drawers in a little pocket. It has this crinkly brown enamel paint job.
