The Silver Jubilee tourer commemorated the Queen’s Silver Jubilee in 1977. It is finished in a silver colour, with the monarchs crown in a special seat-tube decal. This model was probably launched at the Earls Court Cycle Show, late in 1976, and only ran for the one year.
It is not an exotic Holdsworth, built with Prugnat short Type 62S lugs it has simple pressed dropouts and Reynolds plain gauge main tubes, but it is quite rare.

The 1978 Holdsworth catalogue, published after June, does not show the Silver Jubilee.
