During the last war we lived in a large house without electricity. The Fendicks (fairground people) who worked for my father provided a generator and glass cell batteries and this was driven from the flywheel of an open crank Bamford (as far as I can remember) We had an iron foundry at the house, imagine this, which produced castings for Blackstones and Martins Cultivators and made Cambridge rollers and four wheel agricultural trailers. In the machine shop (the stables) were two lathes. One was large and on this a crank shaft for a local brickworks steam engine was made. My father then bought a place down the road from us. This place was a museum. The machinery was old but in superb condition, the shafting was clean and well oiled. Everything was perfect and it was all driven by a very early open crank Blackstone Engine. I will not bore with you any more of this.
