Insert Teds original Sketch (when scans are done) no strut included	October 1948
Insert Anchors Original Plan #1 of Tail (when scans are done) First plan for strut	October 1948
Insert Anchors Original Plan # 2 of Tail (when scans are done) Second Drawing of Strut	November 1948
	October 1949 I apologize for the quality of the image. I'm waiting for a side shot. This first strut was a single piece of formed steel. which immediately proved unable to withstand the stresses required of the prop shaft at high revolutions and the stress of the propeller against the water
Insert photo when available	April 1950 Anchor then discussed the alternatives with various suppliers and they tried welding two steel plates together. This was better. but was too stiff
	May 1950 The team devised a V strut that worked pretty well. Well enough in fact to Break the World Straightaway record, the Gold Cup and Harmsworth trophy
	In 1951 Anchor tried a solid forged piece of 4130 steel and ground it to down to the required shape. This strut was used in the the 1952 World Record Run of 178+mph
