Looking for information on Radiogram

I have just purchased a radiogram and cannot find much information about it.
The only markings on it say its a Gerrard, made in England. It is a cabinet style, and on the left hand side at the bottom, it has a side cabinet with 3 shelves that close back with in the cabinet. It has 3 record playing speeds and on the radio it has STC marked on the top of the panel. I think it may be an RC70 or RC80 model from 1950, but i am unsure. I am in the process of getting this restored. It has one large speaker in the cabinet. Can any one help me in identifying this, and confirm if the model and year are correct, and how much it might be worth once restored to original.
