CWC Serial Numbers
Have you read the "Cleveland Welding S/N Project?" thread on this forum? I've found it to be very helpful in dating my two CWC Roadmasters. Your Luxury Liner has a suffix of Cw, which according to post #63, by RMS57, broadly dates it to 1947-1949. With a prefix of "A", it may have been built closer to the earlier date.
