A pair of maps with the vice-county boundaries overprinted in red on the monochrome 10-inches-to-the-mile Ordnance Survey sheets. North Sheet covers Northern England, Scotland and the Scottish isles. South Sheet shows the midlands, Man and southern England. Northern Ireland and Eire are not covered.

Although it will resolve most queries, it has to be said that the small scale will still leave you unsure if your record is near a boundary which doesn’t follow a real world feature like a river, or if that river has moved - or if your specimen in a fish caught from the river itself!
