It's interesting that I've probably walked over some of those, and not realized what they were; I thought coal normally went into the cellar through grilles. I assume it wasn't the same for such covers, but a lot of ironwork, specifically railings, in Cheltenham was removed for the (second world) War Effort. That apparently was never useful for anything other than propaganda/morale value. I've had the impression that must have been more than most places, judging by the remnant bases. It doubtless did less damage than more recent Planners.
