Door sprung draught stopper

[cynic]

Some time ago I came across a sprung hinged wooden strip across the bottom of a door. It had a short projection from the edge of the door opposite the hinges such that when the door closed the projection contacted the frame rebate and pressed the strip down against the floor creating a tight seal. I have never encountered one since but now have a door with an uneven floor which would be ideally suited to such a device. Google isn't very forthcoming with the usual queries so does anyone recognise the item and can give me a name/manufacturer/source? All help gratefully received.

I remember them from the 1950s, but haven't seen one in decades.

"Stops heat, cold, draughts, dust, bushfire embers and insects."

Shame about 15' floods, innit.

Sort of work but if the floor over the arc of the door has a high spot that sets how low you can have the brush set. Which can mean the brush is not in contact with the floor when it is closed.
