A superb, large, parabolic mirror which throws the most amazing distorted reflections.
By Clarke Chapman & Co Ltd, who are a company founded in Gateshead in 1864 and still in operation today (originally this piece would have had a military use).
A perfect wunderkammer piece, or for the military collector.
The mirror is glass, silver backed, with a lead backing on which various data is printed.
A rare and unusual thing.
