Well the reason I dropped it here was so I could get back to it later. The area is much bigger then you would open in Potlach, and my own process has been to select an 'error' on geofabrik and follow the link in the detail to centre on the area I need to work on. It's worked well a little further over and I've cleared a lot of some areas .. Evesham is next
osm.org/?lon=-1.99969&lat=52.08041&zoom=12 is the map area ( you borrow the lon/lat/zoom element from the link )

Now I've got back into the wiki .....
80n created a lot of the original data in those areas. A lot has been edited since, but the original nodes are 'tainted' :(

Commenting on my own post!
Location is *NOT* Willersey ... we are in Worcestershire!
