Hi Dougal99
Del is correct in saying it is a Marks Model Boat kit of his ASD Tug that I built.
The model has many working features such as winch,monitors, radar, nav lights and instrument illuminations.
I changed the scale slightly to 1/35 from 1/40 so that graupner figures could be used from my bits box.
All the hand rails were re-engineered to new scale, the wheel house was made taller too. The props were Jotika asimuth units 50mm.
I hope this helps you, however it was a challenge to get this up and running in such a small space
