I've just acquired a an Ensign Speed Reflex camera and noticed that Houghton Butcher sold them with with a lens test chart, I don't remember seeing anything like this before. Unfortunately the chart for this camera and Aldis-Butcher f3.4 4" Anastigmat has long gone.
From the Houghton Butcher advert for the camera 1929:
THE LENS EQUIPMENT.
The standard equipments are the Aldis-Butcher f/4.5 and f/3.4 anastigmats. They are personally guaranteed by Mr. H. C. Aldis, and each is accompanied by a photographic test chart showing the absolute perfect covering power and definition obtained. These lenses, which are made specially for this camera, are a very real optical achievement.
