No - I can't find anything either. (Having said that, the ship took part in the 1940 actions against Dakar and there are pictures in the IWM, but only, as far as I can see, taken from her).
I have a feeling that I read 'somewhere' that the conversion was never finished - that the ship was in a 'bad state' and that it wasn't worth doing.
She was modelled by three producers. I have the old HM model of her as a trooper. Let me know if you'd like a picture
