Here then are the abbreviations Harding uses in his Blackburne book (note, I have to use preformatted format to get columns aligned):

I have to comment that I find the periods somewhat distracting and unnecessary. Also, if conjunctions are felt necessary to go into the acronym, then a lowercase letter would be my preference. Like any good system, Harding’s abbrevs are fine and very workable, but my preference is for Zavaratelli’s conciseness.
