A very nice large heavy Reconnaissance 20"- f 5.6 - Anastigmat Lens ser no TT284280 - 14A/2271 which may be by Taylor Hobson Cooke , ? believed to be approx 1939 - 1945 or in date . I found a reference to Spitfires use , the lens size 14 cm wide approx at the widest point x 9 cm high ,lens glass 9 cm clear area , 2.2 kg unpacked glass is in very fine condition in my opinion, from my collection of small items , sold as shown. I am having a clear out in the house.
