Cannot see a brand name. Its a strange design it came with brackets to strap to the handlebars but they would have been in the way of my grip.
I have had to strap them to the bars using the bar tape and string. I then lacquered it all to keep it water proof..
Ive just returned from a trip to Chateaureax in France. 270 miles over three days.
Note the Continental tubs which did a fine job throughout.
