Blimey! What I particularly like about it are those painted-over turn indicators (not flashers, originally). Most had an elongated arrow in the glass, but I have a distant memory of seeing a bus with one that read "RIGHT" and the other "LEFT". They were always paired with matching indicators at the back, set quite high, often in the waist-band. You saw the same over the number plate of RT buses in London, painted over in black, which were the only case I can remember of a vehicle's left-hand indicator being positioned on the right-hand side, along with its single red rear light and separate single orange coloured brake light.
