I thought it is meant to be read, any K3 _up to_ S/N 211 may need the
modification. I take it that after that point in time a change was
made. Or am I just reading things backwards? Similar to how a number
of modifications were available/needed for early model K2s whereas a
late model K2 had very few mods / re-work needed.
