I just put a pair of the stainless steel ones with all fittings, bolts etc on Ebay if anybody needs some. Whats more, they are free from scuffs and scratches!
I'm going back a few years now but I spoke with the manufacturers and if I remember rightly they were made by Motad. Whoever it was didn't make them for long as at the price they had to sell them they were losing money on every pair they made.
