My thanks to Flash and Mark Stevens in helping to unearth a little history on this very underrated London builder. You can see the result at http://www.hetchins.org/purves01.htm Mine is the gunmetal grey track iron did a 25.47 in our local evening club 10 on pressures the other night. Can't wait to get the sprints built.
Best wishes and be lucky. Michael Butler Huntingdon UK.
