Just searching for brickworks at Mablethorpe and came across your site I noted you have put a lot of effort into your research and thought you may be interested in the notes below that I found while researching family
1901 • Mablethorpe, Lincolnshire, England.
William Storr age 39 years - birthplace Scothern Lincolnshire Stationery Engine Driver in Brickworks.
Mary Ann age 43 years - born Benniworth Lincolnshire.
Son George Storr age 14 - born Benniworth Lincolnshire. No occupation given.
He was still working on this engine in 1911 census and his wife was then listed as brick and tile worker.
Maybe it was on wheels or had foundations – I know they replaced windmills sometimes.
