These badges are from the Observer Corps, Irish Defence Forces. The Corps has now been disbanded so to get a set like this is rare. The staybrite badges were a pair, but the brass was only issues one sided. The bird on the collar badge is a crane, and you can see it is holding a stone in its claw. The reason for the stone is that if it falls asleep the stone will splash in the water and waken it, so the Observer Corps was ever vigilant.
