If that were my razor, and I had those stones (which I do, as luck would have it), I would start by taping the spine with at least one layer of tape (personal preference, you really don't have to), then start with a rolling x pattern on the DMT 1200 until the bevel is set. The DMT will make quick work of that task unless it's seriously dull. Then I'd move on to the Coticule and form a slurry with the rubbing stone, remove the tape at this point if you wish to do so, within fifty passes (could be much less depending on your stone) the scratches from the DMT 1200 should be gone. Wash off the slurry and rewet the surface of the Coticule, twenty or so passes ought to bring the edge up to a nice hair grabbing sharpness, but you really can't over hone the edge on a Coticule so you could just keep going until it no longer gets any sharper. Then I'd move on to the Escher for 20 or so passes with very very light pressure for the final touch.

Hit a plain leather strop for 100 or so passes to soften the edge a little and have a test shave.

If it's not quite as you'd like it, start back at the Coticule with water, and progress as necessary.

Very nice blade! I really have a soft spot for those old chunks of English steel, and that one seems to be of excellent pedigree .
