This is my tug boat that I built 40 years ago, It is older than my youngest son. I will let the photos talk, The real tug was sailed from South Shields to Australia as a top sail schooner, the propeller was removed for the trip. It also towed the last sailing ship into Sydney harbor. It was sunk twice during its life once under Sydney harbor bridge and was lifted 3 years later with the death of a diver ,she was the first tug to work in Pt Kembla and worked in Newcastle as well. The last time she was sunk was trying to help a ship in Port Kembla harbor and was cut up on the spot. I dived in the sight and found a copper fitting very eroded by time and cast the bell for the model from the remains.So here are the photos.
This photo shows the forty year old electric motor which incredibly still works
