You can get dirty harry levers in black, gold, silver, green and redishpinky colour from here  cyclesportuk The site takes a wjile to load but be patient thats the exact page you need     I ran a gold finger lever and it can assure you it was pap i ran it with an oddy cable and a fly brake with plaz pads that was set up perfect the brake worked and did hold but there was not much power in the brake when i needed it.   Edit: here is the pic from the site
