I've used these to good effect with several small speakers including Proac SC1 (for which they are particularly recommended) and Totem Model1s. I did previously have the original Target R4 stands and these Sonus badged ones are identical. However they suit suit my current speakers and aren't tall enough.
They are in excellent condition, although they don't have any caps on the nuts in the top plate and some of those nuts are a little bit discoloured /rusty?).
They have spikes on the bottoms of course and - quite rarely - I also have the original packaging boxes for them, although as they weigh in at about 25kg each, so that would probably be quite an expensive (though not impossible) option and I'd have to look into the costs.
Top plate size = 21.5 x 15 cm
Bottom plate = 30.5 x 25 cm
Height = 64cm with spikes
