H ... is for (water) hydrant; for the location, see <a href="//commons.wikimedia.org/wiki/File:The_valley_of_Shield_Burn_-_geograph.org.uk_-_1110555.jpg" title="File:The valley of Shield Burn - geograph.org.uk - 1110555.jpg">1110555</a>. I am indebted to AlastairG for the following information about the numbers in the sign: the upper number (80) gives the diameter of the feed pipe in mm; the lower number (10) gives the distance in metres from the sign to the manhole or metal cover over the pipe.
