Whew! I hope the dust has settled and it's safe to come back into the room.
Please tell me if I'm breaking any rules - it's getting a bit convoluted - I'm posting on this one because the new third thread appears to have petered out on the 5th - and turns out not to be noticeably much more revealing than the other two.
Oh, and can I assume that "specifying the clue in your post" means, eg., "10a - (9) " - rather than typing out the whole ruddy text of the clue each time? - if the latter, as at first I read it (and which appears on re-reading and reflection to be increasingly what was actually intended) it would be hugely onerous - some clues are three lines long - Norah, Malone - do please reconsider this - we don't all need to be punished like He Who Must Not Be Named!
Well, I'm stuck at the last hurdle:
I have carried out the first part of the instruction, understand the colours, and the specific notation to be entered in the side-flaps, and have carried out the second part, using the seven specific technical instructions, starting and alternating the two colours (bottom>top) in the conventional way, but the 7 letters that I move in this way do not spell out anything recognisable (in spite of buzzb's statement that they do in one of the other threads).
I even know what goes into the barred-off cell as a result of this - but I have no answer.
I understand the title Harry East in terms of the question WMII? in a particular literary context - the final position of the moved items in the grid is indeed M in a different sense - but if the answer is supposed to be Harry's M - TB - I can't spell him out - nor do I understand why the special literary context and title are relevant - I wasn't aware that this thematic activity was indulged in by these Ms - in context they engaged in a much more physical activity - the only vague link I can see is that Google tells me that there is a prominent TB who is a current star performer in each of the activities - sedentary and physical - but two different people of the same name.
I'm obviously missing a vital layer of coding or allusion - can someone help me with a hint or two, please?
If I've revealed too much, apologies - I'm finding the shifting sands of the etiquette on these three apparently almost identical threads, with stuff appearing and then being erased, but not reappearing on the next supposedly more indulgent thread, very confusing.
