Wanted Speedmaster Backrest

I don't know if you are looking to buy new, but have a look at this company.

They are based in Spain but their bars look better than the Fehling ones (in my opinion) and are cheaper. The manufacturer appears to be a company named Spaan. Some of their product are available on Amazon but not the back rest.

 

One here not that cheap though
