Ok Here are some of the guesses I have come up with. They are based on looking at the script from different lighting directions over a few weeks time. The most obvious being J DILL, or J D W......alternately possibly JDUL, JOUL or JOW
Now if the first letter is not a J then a Script "T" or an "F" So besides changing out the J in the above guess one could substitute a "T" or an "F" for the first character TDILL, FDILL, FDW, TDW, TDUL, FDUL, FOUL, TOUL, TOW, FOW, & TOLL
