DenverJunction signal box rarely saw use in its later years

spending most of its time switched out being located only a couple of miles south of Downham Market. It stood at the point where the branch to Stoke Ferry branched east from the King's Lyn line. It was manned when rail access was required as far as the sugar beet loading depot at Abbey that itself was rail-connected to the Wissington beet factory via a light railway that was once part of a much wider network. With the transportation of sugar beet being transferred to road in 1982 Denver Junction was no longer required so it was closed. It was a Great Eastern box with an unknown date of construction unless anybody can advise me.
