The guide I look at actually shows both 2-blade and 3-blade versions of the '1/2' model, with the picture I included from the 2-blade pattern section of the book. Pattern #s listed in the book vary accordingly, with the 2-blade '06245-1/2' and 3-blade omitting the leading zero as '6345-1/2', by Case's convention for including # of blades as a digit in the pattern#.
Duhh….I totally overlooked the 3 in my reference.
The 1/2 suffix indicates an option as a main blade on two blade patterns, or options on secondaries on three blade patterns. Typically a pattern number without a suffix is the “standard” configuration. The 6245-1/2 would be a two blade but which main is the standard I don’t know.
