Many thanks for the helpful responses. The model was on sale at a local auction and not attracting much interest so I bid and bought it on impulse as it looked good value for the money. I did think it was a quality plastic display model but when I went to lift it I found it was extremely heavy and weighted towards the stern.
Following the responses I lifted off the superstructure and unscrewed panels at the stern which revealed electric motors and associated wiring etc. There were no batteries or any control box that I could see in the bow section but there are wiring connections and a speaker along with plastic tubing for, I now presume, the fire fighting equipment.
The vessel is the Tito Neri made, I believe, by Graupert. It is 100 cm long and around 33cm wide. The main mast has detached as have some small items such as radar and some ornamental lights but it would not take much to repair it.
I will probably try to sell it on but I am sorely tempted to get it working and try it out but have no idea what additional equipment would be required. Any guidance would be appreciated. If anyone can let me know how to attach photos to the thread I will post some.
