989. Time clock keys
990. Animal restraint device (?!)
991. Gas light and valve tester - probably a good thing it's

993. Scratch beader
994. Replaceable hammer tip
989, power keys, removable switching for machines, often used on
990, flow and return hose crush?

it will not rotate.
991 A collection of lubricators. Probably a display board of them. Some look

992 looks like a coin lock from a vending machine.
