On April 1, 1986, the men's javelin (800 grams (1.76 lb)) was redesigned by the governing body (the IAAF Technical Committee). They decided to change the rules for javelin construction because of the increasingly frequent flat landings and the resulting discussions and protests when these attempts were declared valid or invalid by competition judges. The world record had also crept up to a potentially dangerous level, 104.80 metres by Uwe Hohn. The javelin was redesigned so that the centre of gravity was moved 4 cm forward, further away from the centre of pressure (the point at which the aerodynamic forces of lift and drag act).

Are there any pictures or descriptions of the old rough tails? Like old catalogues or something?
I have a pretty old Sandvik Champion that looks like it was re-built from a rough tail and would like to have a rough tail in my collection.
Also you should follow me on FB im at 78.41m now and hoping to break into top three at the USA champs. Take a look
