Amazing how stories go around!
The removal of the Wills Founder engine to preservation in Derbyshire was partly funded by the Science Museum.
Following the successful first phase of this operation in summer 1976,
PDMHS was asked by the Science Museum to evaluate the possibility of removing the Sir Francis engine also.
You must bear in mind that in those days Francis level was not expected to remain open.
In December 1976 a group of Wills Founder veterans took representatives from the Science Museum into Sir Francis to view the engine.
As a group, we would have liked the challenge of recovering the engine (if someone else was paying...), however, we never really thought it would happen once we showed the layout of the engine.
The marvel of the engine is not the iron bits but the beautifully built chambers that it is housed in.
The Science Museum people could see that the engine was not very important compared to the cost of building a replica mine to put it in and so the idea died (fortunately).
Even then, someone had been unbolting odd bits of engine and removing them so the thing wasn't complete anyway.
