b. Convertible Coupe and Estate Wagon
Frames
Frames for
convertible
coupes and estate
wagons are identical in general design, num-

parts with closed body frames, but additional
reinforcement is added to compensate for loss

All series frames are very similar in design,
relative parts being merely made longer or of
thicker gauge, as the need rquires, to take care
of longer
wheelbase.
The principal structural
difference between series is in the cross mem-
