This larger than normal collectible Roof of Africa 1977 Maseru race EPNS water jug measures 23.5cm x 17cm x 26.5cm high. The jug has normal age related wear on the silver plate.
The Roof of Africa off-road race started in 1967, although bikes first raced in 1969. There are not many motorcycle racing events of any kind that are this old. The TT on the Isle of Man is one, and the Baja down in Mexico another. There are probably one or two others like the ISDE and the Six Days Trial in the UK
