chubb safe no32

Thanks for that Tom, I never thought of a day lock which I've only seen once before and that was on a huge Milner in the City Collector's Dept. of the Glasgow Corporation. It was a spring latch which I assumed to be an emergency closure device against hold-up.

I'll guess that the top left handle is a pull handle and top right the keyhole shutter knob with the cross-locking bars round handle below.

The pivotting seesaw has connections to the safe boltwork on both sides of the lock - that is thrown by the drop handle while the central knob is for moving the bolt stumps into the fan levers

Just changing the topic ever so slightly back to safe moving. This is a highly unsafe procedure. They do not have high-visibility vests on.
