I hope this makes sense.
If you look on GE there is a staggered cross roads, or is that cross tracks, on Bowsers Lane with a large building to the north east of the track that runs north.
It has what looks like white vans in front of it. (2009 map)
The old barn can be seen in the field to the south and has what looks like a kink in the roof, because that is exactly what it is !
The entrance was off of bowsers Lane.
As I remember the building was across from there.
