In 2020 Onoto once more teamed up with TMB Art Metal to work on a pen part made from metal recovered from a Battle of Britain fighter plane. Previously we had the Spitfire, made of Duralumin from a wing spare removed from P7350, a surviving MK2 that required the part to be replaced to remain airworthy. For this pen less metal has been used, coming from P2725 TM-B, the Hawker Hurricane Mk1 flown by Sergeant Ray Holmes and famous for being crashed through the tail of a Dornier Do17 bomber which looked like it was flying at Buckingham Palace. The incident was made famous as the German plane was filmed falling out of the sky and crashing on to Victoria Station. Alas P2725 faired no better and Holmes had to bail out. He not only survived the Battle of Britain, but also the war, dying in 2005 at the age of 90.
