<p class="x_MsoNormal"><span style="color:#1F497D">Unfortunately it seems that the serial numbers were not available in the drop downs original traveler when it was first inspected back in November , subsequently it seems that the SN was scratched out on
the part so as a result we may have lost traceability on what end group ended up in this cavity

left undefined in the cavity inspection traveler</span></li><li class="x_MsoNormal" style="color:black"><span style="font-size:12.0pt">After the end-groups SNs were added to the drop-down menus, I was informed yesterday that some of the EG SNs were "scratched out" and not visible.</span></li><li class="x_MsoNormal" style="color:black"><span style="font-size:12.0pt">This morning, I asked Ashley to check the thickness of the FPC flange on cavity C75-RI-011 and she sent me the pictures below which indeed show that the end-group SNs were scratched
out and replaced by some other nomenclature</span></li></ul>
