Signed on the first draw, ‘Chadburn Brothers, Sheffield. Opticians to H.R.H. The Prince Consort’ (Prince Albert, husband of Queen Victoria). With a main lens of 42mm diameter, 80 cms fully extended and 21.5 cms closed. The first draw has a short pancratic eye-piece giving magnification powers of between 26 x and 32 x. There are sliders to both ends, the lenses damage free and in good optical / working condition throughout.
It comes with a book titled, ‘Albert the Good. Scenes in the life of The Prince Consort ‘. The book is in very good condtion and interesting as the style of writing of the period is very deferential and in awe of the subject.
Circa 1850s (Prince Albert died in 1861).
