Gadge is spot on with regards to how the offset 4 blade system would work..The odd thing though is, what was Victas true intention for this, since the Specials nor Rotomo were fitted with side throw chute or catcher option until the Sheerline 3 years later. Directional throw Would be most likely. Incidently, of the few hundred specials, Ive passed on, not one had 4 blades fitted. Why?
