Here's an update - I found that there's actually no need to get involved with the focussing helix. I removed the front and rear lens assemblies, followed by a deeply recessed threaded retaining ring. Removing this allowed the aperture assembly housing to come out through the front and I could then set about dismantling and cleaning it (I use carbon tetrachloride). Reassembling the blades was a test of my dexterity and patience, but using the thin metal ring/shim to hold the blades in position on the front slotted piece was a big help. I then offered up the front piece and assembled blades to the body with the fixed holes that the blade dowels locate in. Attention must be paid to the correct location of the two holes that are threaded to take the aperture blade lever that runs the length of the lens.
Hope this may help others with the same lens.
