Whoa, I didn't realise these maps are online! When I was in England I was blown away by the detail of the OS maps. I managed to find Broomhill Farm which as you say is clearly shown (although I think it probably took me a lot longer to navigate my way there than you, haha ^^;
What an amazing feature where you can overlay modern satellite images and fade between the historical OS map and the modern photo. Thrilling!
Many thanks, Neil!
