I've posted my bike a month ago not really knowing what it was other then a Firestone by the front badge. I've searched all over the internet and forums and couldn't find anything concrete. Well I just got my report back from the people/person at NBHAA and they've identified it as the 1956-1/2 Firestone Speed Chief Promotional Model. The Promotional Model because of the white paint with red trim, gold edge striping and a few other select options that I don't have on this bike...yet. The original models were green, red and white. I'm very pleased with the detail report by HBAA and I can sleep easy and start on restoring this baby to original! Enjoy!
