SHELDON suggests, that "Shimano 5-speed and 6-speed shifters are made to index with the 5.5 mm spacing between sprockets on older 5- speed and 6-speed freewheels", and I know that Shimano 6/7 Speed shifters are compatible with 8 speed cassettes, so, hopefully the indexing should work. On top of this, he says "Up through 9-speeds, all cassettes use very nearly the same wdith of sprocket teeth, and will work with 7/8 or 9-speed chains." I'm hoping that this means the 8 speed chain that I propose to purchase, to go with my 8 speed cassette, will be of the same with (minus the protruding rivets on the old one).

You're right, it's not HN... I may have scout around E-Bay for one, but since I won't have it on my solo (which I ride much more), I expect I'd just get a bit confused...

You are almost certainly correct in this. The cranks (cotterless, post 1982 since the crank-extractor threads worked) and the rear derailleur (Shimano!) are definitely not original, so I wouldn't be surprised if the front DR was not as well.
