GBW 22000 to 22028 were 50' RBLs built by North American Car Corp.
approx 1966; does anyone know what type of roofs they had (presumably
Pullman Standard or Stanray)? I wondering in terms of which style of
the HO Athearn 50' NACC Box Car is a closer match. Sorry, prototype
photos seems elusive-- all I have is one poor-resolution image which
doesn't doesn't include roof details.
