I bought a similar set from the same seller a few years back for my V7Sport. They're not just old stock but are rebuilt as the seals don't stand the test of time. They were what was on my Sport when I bought it in 1978 and were good then. Don't see why they wouldn't be good now. My set were cheaper (about the price of a new set of Ikons) and the seller brought them in his luggage on a planned trip to Germany and sent them from there to save postage!
