Peacemaker I- created out of a 1961 GM motorcoach and the upper section of a 1950 General American Aerocoach observation coach,
Peacemaker II -created out of a 1955 GMC Scenicruser, and a 1949 General American Aerocoach observation coach.
just doing a bit of research on this there are some fantastic looking old coaches and buses from America.
