Random question here...

I know that the "H" sign stands for Hydrant, and that the numbers
above and below the H specify bore and distance respectively. But I
have recently seen a few  "HD" signs, again yellow, with numbers above
and below the H, and with the H and the D merged together.

Purely out of curiosity can anyone tell me what these mean? Also, is
there any way of knowing whether it is a new, metric sign, or and old,
imperial one?

Cheers,

Ben

Hydrant double, Double outlet.

Metric signs will have bore in mm so will be significantly larger.
