re: WTB - Breitling Colt - Thunderbirds by watch_a17350 on Aug 26,2007 07:45 PM Hi there. I have perhaps what you refer to as the sister. Though I believe it to be far more rare(only 50 or so). Please feel free to Email me at dhactennis@aol.com. I'm interested in finding someone who will appreciate this exceptional timepiece. i will send pics directly.
