Under JBL the monitors were redesigned, with new, cast aluminum speaker frames and slight modifications to the crossovers and tweeters. The result was the 813C. However, in the overlap, JBL/UREI put out some 813s with the modified crossovers and tweeters that used up the original stamped steel frames from UREI. Those are known as the "UREI 813B/C." The 813B/C speakers I use at work date from 1989, during the overlap, and the 811C speakers at home date from 1991, after the overlap.

Ahh... thanks for the clarification. I thought you were using shorthand to tell me you were using both the B and C versions. I was unaware of the B/C version.
