My one had a cosmo racing sticker on. I peeled it off as I don't like stickers on things. I'm sure I have the fitting instructions in my shed somewhere, which will confirm whether it's an actual cosmo brace.
Here's a photo of it on my car:
I removed it last weekend, so I'm going to give it a clean and I'll get some more photos of it, if you're interested?
£150 posted? I'll take some photos when I get home tonight to show you the condition of the bars. It hardly weighs a thing, so shouldn't be too difficult to send through the post.
