Tanz, I guess that was a brand new price? I just paid £8 for a secondhand pair on eBay but plus £6 p&p. They are described as from a Rover 800/820/825/827 1997 R reg.
Works great, so I also have one spare for about £7 but I was going to wait until the next Stoneleigh / Donnington event before offering it up for sale.
