Appointment with Nick

I think I finally have an appointment with Nick to see a bike that he told me about a month ago. It's a 1953 Triumph that's torn apart in his friend's basement. I think it might be a 650 Thunderbird like what Marlin Brando rode in "The Wild One". It's missing the tank, but I know where to get one. I just have to figure out how to keep dad from claiming it as his.
