A collection of lantern slides and research notes compiled by a lecturer at the University of Manchester to illustrate lectures on the subject of engineering. The lantern slides show an early Renold Chains promotional stand and marketing material created by the company, along with images of the Engineering Laboratory at Manchester University in the early part of the 20th Century, and views of the Manchester Ship Canal during and after construction. The research notes were created by the owner of a machine tool company in Altrincham.
