Update on post #30. The photos in the post were of George Ellison's (now Tufnols) on Wellhead Lane. Opposite the factory was a former Ellison's site that was in the process of being cleared The gates into the site had the 'E' Ellison logo and the pillars each side had lamps on top, exactly the same as those on the factory entrance gates across the road.
Today the site has become a bus station. The gates have gone, being replaced with new ones, but the two lamps remain on top of the pillars. Would have liked to have had that 'E' logo, hope it's gone to a good home.
