That is not Bill Madaniel's logo. The letters are correct, but Bill only used one logo, never anything else. He signed a few buttcaps as well. That logo and the work done in that cue is not Bill's, in any shape, form, or fashion.
Dave is correct about the "C" in Bill's logo. It signified his partner at the time, Tommy Clements. Tommy and Jess June now own the complete McDaniel shop. Bob and Cathy Ryan own the name "Bill McDaniel" as far as cues are concerned.
