All I found was a list of planes on wika and they listed the Sterling as one
When Marconi had it it was in better condition than this not sure but a building like this was the works canteen.
a brain cell has just fired up and I remember one hot summer working there we made a bomb tail fin out of some sheet metal and put it in the pond near our building
Then pointing this out to our manager he said the hot weather was lowering the water level and the bomb was showing now he said I have to send every one home and get the bomb disposal people in. What a great couple of days we had off Work with pay.
They never found out who made the bomb or put it in the pond.
i hope we are not going to get into trouble going off topic?
soon have the last part of the engine.
