We were very fortunate to be given permission by The Wheatcroft Collection to photograph a copy of Manual D656/21a. This is a series of hand painted images on clear acetate pages comprising the major components of a Tiger Gearbox. Each page has an element of the gearbox, and when the pages are turned the gearbox is 'built' or 'reduced' depending on which facing page you are looking at.
The animation below allows you to see this effect: either by running a cursor over the numbered buttons to hide/reveal, or you can drag and drop the components to separate them for closer inspection. The arrow button resets the view.
