The panel above, and the three panels below are situated above the first floor level on buildings opposite the Shires Shopping Centre, High Street, Leicester. I don't know anything about them, but they look to be tube lined and appear to be late 1920s or early 30s.
M371 has had 9 of its original tiles replaced - 6 extreme right and the upper 3 extreme left. M373 and M374 appear to be made up of glazed and decorated bricks as opposed to tiles.
