"My dad found this in his house when he got back from holiday. No idea how it got there but that’s a different mystery altogether. Looks like a syringe but the middle (green) bit has no hole at the end and moves up and down into the clear claws at the end."
A: "Its a pill dispenser for pets, the pill goes in to the claws and you use the plunger to shoot the pill to the back of the throat"
They also used to have firing ports in the billboards along the highways.
Ha my thought initially but realized it is being used to cover a hole...(Probably a location for a control panel in a different situation), since it fits so well
We have these in our elevators as well. There used to be a telephone mounted there to call the front desk in case the thing got stuck. Later they got obsolete because there had to be automated warning systems
This is part of the weather station system. There is also a wind speedometer above the plaque. And I confirm that the upper temperature is air temperature and the lower temperature is the road. Warnings, for example about black ice, are also displayed there
