Set Of Victorian(?) Post Box And 2 Postmen, one with head broken, Box 62mm Tall

A set of 1 post box and 2 postmen in (I think) white metal. The crouching man has his head broken off, but easy to fix. See photos. Unknown scale but box is c62mm tall, so maybe around 1:32. I believe it says VR Post Office around the top of the box.
