RCA matrix code KCL1

Best of the Country Fiddlers Vol. II on RCA Camden Pickwick has phonographic copyright 1973. The matrix code KC would be 1980 Camden, but L1 would not fit (7", New York.) If the 1980 date means lacquer cut in 1980 then the TG. in runouts means McLear Place, if 1973 is release date then lacquer cut at the same studio was at RCA Studio, Toronto. Can anyone help with this and other KCL1 releases? Thanks!

Does it reference RCA Limited or RCA Inc.?

My guess would be that this is a catalogue number prefix, independent of the matrix number scheme you refer to.

Thank you both! Clayfoot, I think that you are correct that itsa catalogue number independent of the matrix number scheme.
