I spotted a gap of less than 3 hours from top to bottom of the first page only the other evening. Too many posts are coming in for a single forum to handle and perhaps it is time to develop a system so IDed topics can be shuffled out quickly? Something Frank suggested recently. Also dividing up topics by type, or country, or... something I suggested many moons ago.
More mods are needed to handle the housekeeping...
Anyway, I have had something similar pass through my hands, which I thought was Sowerby at the time, but could be mistaken.
