Comments about the data

differences uncertain between 449, 452, 463, 469, 479
options: Breguet hairspring*, separate escape-wheel cock*, shock protection**
(* scarcely or never, ** often or always)
Assignment troubles:
Flume lists 3 balance staffs assigned to calibres, Ronda lists 4 staffs for all calibres, LeCoultre data sheets mention no differences.
Calibres specified in data sheet with shock protection are occasionally met without.
Calibres specified in data sheet with optional shock protection are never met without.
