also, at about 8 through to 6 o'clock, does it look like there is a gap between the drum liner and the hub?
I'd replace the wheel bearings at the same time Ted, bit of corrosion going on there. The retainer ring holding the sprocket carrier on can be a bitch to remove without the special (and even with it sometimes) so watch yourself doing that one. Reverse thread BTW as well. Check for arrow showing direction to undo.
I guess it depends what your intentions are Ted in terms of cost/value use and aspirations. Me, I’d dismantle, vapour blast and rebuild with new rim, spokes, bearings and dampers. You may even need a replacement rear sprocket. I’m from the do it once, do it almost right school, so don’t listen to me. The cost to rebuild both ends of my 550 F2 ran out at about £600 including tubes and tyres. Just saying…
If buying exhausts DON'T buy the brackets as they are repros (unless DS has some originals) and are not the right angle to allow the exhausts to fit properly. I had to bend my BILs brackets to match my originals the other week, the connecting tube at the rear wouldn't fit, he had constant exhaust blows from the manifolds etc. Find some second hand originals and have them powder coated. The upper brackets aren't too bad but the lower ones are well out.
