Dear Atame; From my research the keys you picture
K1 modern die cast alloy ( late 1970 to current)
K2 steel? more likely plated brass ( the leg iron key was) early 1970's
K3 early key to suit steel ( wrought iron )cuffs
The linkage on the bow was original fitted into a hole and riveted in place. Cuffs were cast where this linkage was an integral part of the pattern and were cast in steel just as the current alloy cuffs are integral( not familar with an actual would suggest 1950-1970's )
Also see my message under "Hiatt or Hiatts" 02/02/2001 on dating cuff by finish of castings.
