And the Spartan,

A Bellona Class Cruiser
Sister Ships Bellona, Black Prince, Diadem, and Royalist.

I can't seem to find any info for models of this class, but a lot of links group it into the "Dido Class". If they are similar enough, you may be able to modify a Dido Class Cruiser to match the configuration of the Bellona class.

Good luck on finding a model.

There is a compnay named "LEE" from China which has a 1/300 scale HMS Aurora. I just got mine from ebay last week and I am very impressed with it. I do not know how accurate it is, but from the one picture I have of this ship the model looks pretty close. You can get one of these kits between 20-30 us dollars.
