Dowlais Colliery, calculations on motors (book)
Book with green cover and brown spine. Lined notebook with handwritten notes inside. Most of the sheets of paper contain the blueprint copies of the text, therefore in most cases every other page has been torn out. There are a few pages where the text is written in pencil with the blueprint copy underneath. The first page is dated Aug 17th 1927.
