Reclaimed Night Latch
Matching steel cased night latches with original keys. I'm pretty sure they're a new old stock from the 50s or 60s. The knob controls the bolt from the inside, the catch keeps the bolt locked in or out, and the key operates from the outside, and doesn't over ride the catch.
Great original working condition.
