Thanks Ray, think I'll try it with film and see how it goes. I had some success with the leaf shutter and aperture blades in the link above by swabbing with hexane using a saturated cotton bud, so that excess solvent could work its way to the hidden parts of the leaves, than after a few times actuating the shutter, the oil was showing up on the other side of the blades. I was planning to take the leaves out but the oil contamination wasn't too bad and I was too keen on making the camera work again to go any further out on a limb than I already was - I had reached the point of not being able to figure out what should come off next and what would be a really bad idea. All that said, the faster shutter speeds didn't improve noticeably, at least according to the test I'm using, but that may have been down to the escapement too, which started off really not very smooth at all. Anyway sorry, rambling a bit, I could try the same with the blades of the K2 shutter perhaps using IPA to work a bit of gunge out do you think?

That is what I would try first.
There is just about enough access from the bottom,once the cover is removed but you will have to be very sparing with the fluid otherwise it could end up in all the wrong places.

Let us know how you get on.

So an update on this. No service seems to have been necessary. I've yet to see the film proof but I had another go with my shutter speed tester, and the speeds are fine. The difference this time was I used a laser instead of a lamp as the light source. With the lens removed, the curtain shutter and camera body are quite large, so it is easy for light to reach the phototransistor not only as the shutter slit transists, but also at some wider angles as the slit approaches and recedes, so it is illuminated for longer than the exposure time. Can't get that with a laser, which was a pig to line up, but worked a treat. As ever I owe it to something read on the internet a few weeks ago, someone using two phototransistors set in deep tubes to reduce this problem. I used a laser on a spirit level from Aldi to achieve the same effect. So, now need to put a film in it and give it a go! The rest works fine and it's in great condition, I even have a case and strap.
