Here is some data for your Ce210 request;
c/n 21064953
Seems that it was in Mexico by 2007-2009
and registered as XB-DRX to INTEGRACION D ELECTRONICA Y SISTEMAS SAC.
c/n 21064968 no info on this frame
c/n 21064982 was registered as N7931U from 1986 thru 1995 as a T210R,
But owner or operator name/address is absent from FAA data listings
This frame went off the FAA-USCAR database by 1999.
c/n 21065008 no info on this frame.
Hope this helps.
John
