look for an old Monogram CV-63 Kittyhawk or CV-64 Constellation,,,,,,,,,both kits are in the 1/780 ish size range. Both are sold as -63 or -64, but are really CV-67 in shape.

ps, don't allow yourself to fall for the Testors "CV-67 Georgetown" 1/720 model, thinking that they renamed the Kennedy in model form like they did in the old TV show,,,,,,,,they just put "67" decals on the Nimitz class mold,,,,,,,,and molded it in a bright blue plastic, to add further insult.
