A 2001 XMM SPECTRUM OF RADIO-LOUD AGN 3C 223 REVEALED THAT THE LINE-OF-SIGHT COLUMN DENSITY IS SIGNIFICANTLY DIFFERENT FROM THE AVERAGE GLOBAL COLUMN DENSITY. TWO QUALITIES MAKE 3C 223 REMARKABLE: THE IMPLIED OBSCURATION GEOMETRY IS A COMPTON-THICK (>1.7 X 10^24 CM^-2) RING OF GAS EMBEDDED IN A GLOBAL COMPON-THIN (1.4 X 10^23 CM^-2) MEDIUM AND IT IS ONE OF THE VERY FEW RADIO LOUD COMPTON-THICK AGN CANDIDATES KNOWN. WE REQUEST A JOINT 45 KS NUSTAR OBSERVATION AND 40 KS XMM OBSERVATION TO 3C 223 AS THE FIRST BONA FIDE COMPTON THICK RADIO GALAXY SEARCH FOR ABSORPTION VARIABILITY BETWEEN THE 2001 OBSERVATION AND PROPOSED DATASET AND ACCURATELY MEASURE THE LINE-OF-SIGHT COLUMN DENSITY WHICH IS UNCONSTRAINED WITH THE XMM DATA REQUIRING NUSTAR COVERAGE.
