Set of three vintage scientific measurement gauges, two flow calculating and one tank capacity calculating. Measures 9" by 9", and tank calculator measures 6" by 6". These antique calculations grids are in fantastic shape. They are a great example of how precise calculations and measurements involved in this field of work have been done for many years. Still in the original pouches with original documents.
