Vintage O'Brien Trainers Kids 47 Inch Training Water Skis Adjustable Bindings. Does look like someone removed and glued rubber foot holder back in place. They probably use glue to make sure the screws would stay in well.
They do have dirt and dust and wear and tear. This item is in the category "Sporting Goods\Water Sports\Wakeboarding & Waterskiing\Waterskis". The seller is "hoppe_mik" and is located in this country: US. This item can be shipped to United States.
