A post mill, marked as 'Bilsby Mill, is depicted in this location at the western edge of the parish, on an Ordnance Surveyor's drawing dated 1819. Sales advertisements show the post mill to have been in the ownership of John Pinney between 1786 and 1820. A slightly later map of c.1827 no longer depicts the earlier post mill, but does show a tower mill symbol in Bilsby village, suggesting the post mill had been demolished and replaced by the tower mill in about 1820 (see MLI41488). John's son Robert Pinney is thought to have responsible for the demolition of the post mill and relocation to Bilsby village. The Pinney family are thought to have sold the tower mill to Thomas Flintoft in 1855. White's Directory of 1856 still lists Robert as a miller and baker in Bilsby though, one of two millers and bakers listed (with the other being Thomas Flintoft), suggesting Robert may have still had some involvement with the mill after the sale. {1}{2}{3}
