Off Leith Walk, Lorne, Pilrig, Leith, Edinburgh Attached to a building that once served as the offices for Leith Tramways, whose depot was behind, are two wall-mounted 1950s' British Thomson-Houston (BTH) 'Amber Mk III' lanterns, for 140 Watt SO/H, SOI/H, and 90 Watt SOX (low pressure sodium), lamps. As the building to which the lanterns are attached dates to 1938, clearly, they are not original, although they may just be old enough to date from the twilight days of the trams; the final run occurring on the 5th May 1956. After that, the site was repurposed as a bus depot for a time, until the former depot sheds were used as industrial buildings prior to demolition towards the end of the 2010s; sadly, a GEC 'Difractor' Z8128B affixed above the roller shutter door (visible here) is likely to have been lost when these buildings were cleared.
One of the two Ambers is pictured below; the second is on the other side of the building, in an identical arrangement.
As no cables are seen exiting the lantern, they must pass straight through the bracket and wall.
A large slotted screw at the front of the bowl secures it ordinarily, with two hinges at the rear of the lantern indicating how the bowl would open for maintenance.
The bowl is too grubby and its plastic too translucent to determine whether a lamp remains fitted within the lantern.
