Vintage barrel keys & desk drawer cabinet locks lot - N.L. Co Rockford, USA

Description

Unsure if the locks go with the keys - I can't seem to get them to unlock but maybe some WD40 would help. There is a little corrosion on the keys here and there and a little rust on the locks.
3 keys of various sizes and 3 locks, all the same.
Smoke-free, pet-free home.
