Not my auction, but this caught my eye. Ebay item # 110086585251
Looks like a Simplex, but badged Speidel (which I believed eventually was the re-organized conglomerate which rose from the ruins of many earlier French component companies which did not survive the 80s intact). This post has long square flutes and appears much longer than earlier posts. I wouldn't use it personally, since the fluting extends so far down it would expose my seat tube to the elements and to rust. But it might be useful if anyone has a "too small" French frameset and needs a longer post... It's still French made and of one of the more common French diameters.
