For width of the nose, get a picture from the top--the saddle isn't "ping pong paddle shaped"; instead it tapers from about 5cm outer wide at the tip to 6cm about 1/2-way down the nose to 10cm where the nose meets the body.
On the other hand, the Allay says it is 5cm from the point it leaves the body ( http://www.allaysaddles.com/line/racingsport.htm ).
