In addition I found the small numbers N+ # 1 - 10 on the sample holder that had been scribed in with a scriber. This may have happed previously -- I am not sure. Cleaned and removed all particles from the sample holder. The teflon guide rails leading into the chamber rails, the transfer rod and all interior sealing surfaces for the load Lock door.
