I have been there twice now, I don't generally go back once a place is visited. This is so close to my gaff, you could have come around for a coffee!
It was very open on both occasions I went, did someone see you enter and were trying to imprison you? The 'Pottery' sign has been moved again I see.
There was a lot of stuff from the 60's when I went, some dickhead had dragged down a load of clothing from the attic on my second trip. Even I didn't go up there, too unstable and clothes ain't my thing.
