An NCAR CGM has *extra stuff* stored in the first 32 bits of each record, therefore, if you stripped these out, the CGM is (in theory) readable by any CGM interpreter. NCAR Version 3.00 has a utility that does this, ncar2cgm, that converts an NCAR CGM to "vanilla" CGM format. cgm2ncar does the opposite. 

Hope this helps,
