They are Auto-Maxi Supra No26 Roofbars that fit 4 and 5dr Ford Mondeos registered between 1993-2000.
They have a 75kg maximum load and are made of steel bars section 30x20mm, 1mm thick steel. I'm selling them with everything they came with which is all that is needed for fitting them, an allen key and 8 screws. Check out the link below for more product info.

They are not as sturdy as Thule's but are considerably cheaper, they retail at £49. I used them for transporting up to 5 boats (including plastic boats and a C2) at a time and never had any problems. If you have a lot of boats on it's probably best to tie down the fronts.
I'd like to sell them for £15 and can either deliver to HPP or a race or can post them at extra charge. Any questions get in touch, Thanks Tim Baillie
