US application filed: March 1963

French application filed: April 1962

Relates to: Simplex Prestige (532)

This is it - the Patent that captures Simplex’s fateful move to plastic. A move that apparently led to:

1. (1)A diminution in the risk of corrosion by the elimination of metal elements,
   

2. (2)A reduction in weight,
   

3. (3)Silent operation,
   

4. (4)A more gentle manipulation and less chance of wear.
   

So now you know.
