Yep -seen that you tube clip, its made by Nikki who is also a BVS member and was a great help with restoring my mini-el. Mine had arrived in need of restoration,so I took it down to Bristol in a van to her place. She helped identify what it needed,and in what order. Since there were no local mini-el dealers to turn to, her help was priceless.
Mine was purchased last May off Ebay,and is former property of Maurice Gibb (of Beegee's fame). Shame the last forum got wiped, there was a thread that showed the restoration ,complete with pictures.
