You are quite right, the hut from Auf Wiedersehen is at the sea scouts. It's the HQ of 15th Long Eaton Sea Scouts. The hut is the blue one behind the main brick building. Access to the site is off Tamworth Road Canal Bridge on the Sawley side or off a gated entrance off Clarence Road. You might not rem,ember Clarence Road because its only been there for about 10 years or so. It used to be light industrial land just off North Road, that was actually a mud track not a road. I think there was a tyre yard or something there when I was at the school.
The Long Eaton School, formerley Roper, has been knocked down but re built further back into the site next to the Westbrrok School.
