Our house originally had eight fireplaces but six are long gone so we had
the chimneys capped with mushroom shaped vents. However there are still two
fireplaces which we don't use but don't want to permanently disable for
future owners. I was thus searching for some sort of cap thay would sit on
an existing chimney pot securely enough not to blow off so protecting it
from rain but providing a little ventilation.

But I can't find one. Does such a thing exist ?
