As you can see this is a great example of a GPO Ivory No26 bell set. It is not a reproduction and was taken off a 1950s 1/232. It has no cracks chips or repairs. It is a little lighter in colour to the sides than the top but very minor. It is fully working and can be simply plugged in to a telephone socket. Markings in slot on cover are PX/PX LA 1 and on the line in LR/LH D. It has the screws to mount to a telephone fitted.
