Interior note that the PP9 battery is a little larger than the original and that the battery clip has been bent to keep it in place.
This model which sold for £16 when first introduced in 1964 remained in production until 1967. Today good examples of this radio are worth in the region of £20.
Roberts portable radios have a reputation for their high quality. This recently acquired radio was working when I received it but I discovered that one wire in the ferrite coil had been damaged but when this was repaired the set worked as well as the day it was made.
I have several other Roberts Radios here here here and here
