Did a bit of searching on the net and once I had the right phrase, BINGO!. Lots of, well several at any rate, hits for what look mike the original version. For some strange reason the suppliers seem to be performance/rally/racing sites. The best deal I found is a company in Spain and in stock. I think I'll take the plunge and order one, not sure if Mrs. would be happy with ' just popping down the road to Spain for a part for the car - don't wait dinner, or breakfast tomorrow, or lunch . . .'
Just gone to their site to order and it now says out of stock!
