This is brilliant. I’ve been trying for years to track down these companies. I was the archivist to the Morris furniture company for many years and recently retired. I was also ordered to write the company history!The company held the patent for the balsa ply and initially it was used for doors. It could save as much as 45 tons on a liner. They made batches of balsa ply for the various Mosquito firms. They also supplied wing tanks to de Havilland as well as Mosquito propellers. They also made up the 5V3 aeroply plywood for Ministry of Aircraft Production used in airframes. They were also involved in experimental work with Farnborough on wooden aircraft before the war. Their records are quite substantial. They made a fuselage out of a South American wood called Quipo, but it was found that the balsa was better for production. They were also involved with E. Gomme of High Wycombe, who made tails and wings as well as fuselages. The problem was after the war the various ministries came onto the premises and removed all the wartime record. I believe they went to the Ministry of Home Security
