What I've done is to photograph (on slide film) the Patterson Optical Test 
Targets published by Patterson Products Ltd, Boswell Court, London, UK.

Designed by Geoffrey Crawley, inventor of the Acu-Photochemical range of 
products, to quote from the handbook that comes with them.

Instructions inside.
