A speedo bracket to fit a Smiths / Jager speedo onto a set of girder forks.
 
As fitted to Norton, Velocette and some Webb forks. The fork mounting holes are at 3  5/16 (84mm) centres and are slightly elongated to allow for any slight variations between forks. The elongated holes are small enough that the washer and bolt head hides them completely. 
 
These are laser cut and folded in mild steel and powder coated black for a hard wearing finish.
