classic motorcycle forum

Hi, after a bit of advice information concerning Radial wayfarer panniers that were designed to fit on to bathtub of 3ta etc. I have acquired a set but without the hinges, I have scoured the Internet for information / pictures of the panniers to no avail. Can anyone help with info or pictures showing the hinges so hopefully I can replace. I have found some information of the panniers in an old " motorcycle mechanic" magazine, image below to give you an idea of what I am on about:
 
Many thanks
