That was the Formans Road battery factory.
I started work at Lucas Gas Turbine, Shaftmoor Lane in 1956, and later moved to their Group Research when it was first at Marston Green.
We had an experimental battery section at Group Research and they used to have close contact with Formans Road, as did my section head.
He had bought an ex navy boat and made a new keel for it using lead he scrounged from here and there, and from Formans Road
The asbestos was used in the manufacture of the battery cases.
