Any chance of a photo.
Like silcon chips, they can have many numbers but an actual visual might just give enough to know which is the important one.
Failing that, there might be some clues here:-

I'm not a gambler, but I'll have a
little bet that it's a 22uF 20% job,
similar to one of these:

googled eyes? Time to delegate
Would it be rude to pop it into a bag and post it, a cheque and a very brief note to RS components...
"Tinternet connection down, please post a replacement - keep the change"

It's very much like the small cans on the Rapid link eclectic gave. I note one is marked -

So it may have been a bad assumption on the "V" meaning voltage, perhaps a tolerance.
This is a cap off a PCI tuner card, bent while being removed ( understandable as it's 1/4" over-sized for a PCI card and crammed into a small factor riser assembly ). It looks to me like it's part of the PSU, near a fuse and what looks like a regulator, one side to 0V / chassis, the other to another two-legged regulator looking thing, paralleled with a smaller SMT ceramic cap.
Apparently it still worked okay without the cap, so probably best to leave it that way, start trying random caps if there are any noticeable problems and see if they go away.

the letter V on the site above, used to denote 35V

It is still a bit of a mystery, 22uF 16V would be my guess. Having cut the plastic base support off, there's just enough of the legs left to get the tip of a probe on so next time I'm in Maplins I shall give one of their 'better than mine' meters a test drive
Thanks for all the links.

That's a great way of identifying unknown components - they have all their component analyzers on display. Might even buy one, if I need it enough!...next time I'm in Maplins I shall give one of their 'better than mine' meters a test drive
