Edge's Corner was the final named bend on the Willaston Circuit before the route rejoined the Snaefell Mountain Course at Cronk-ny-Mona, sitting between Cronk-y-Berry and that junction. No dedicated historical page, old map annotation, or race report naming an exact location for 'Edge's Corner' could be found; it does not appear on Wikipedia, Manx Notebook, or the old-OS-map indexes searched, and searches for the name elsewhere on the Isle of Man returned only unrelated results (e.g. an Edge's Corner in Dublin). It is likely a locally-known/club name for a bend on the lane approaching Cronk-ny-Mona (itself fixed at 54.18333N, -4.47583W) rather than a name that ever appeared on an Ordnance Survey map, which would explain the absence of an independent source.
