Hi Mooncrest and chevvron. The Watchman at EGCC was originally on the south side, next to the Kilroe hangar. it was on a tall lattice tower just as you describe. When it was moved to the north side, just north of the 05L threshold, a similar tower was built for it. The St.Annes Watchman, which replaced the Marconi 264A, was on a similar tower too. All 3 towers had the steps leading to the top.
