The J4S was a complete redesign of the J3S for lighter weight and lower profile. It's been said this was in part due to the beautification campaign led by President Lyndon B. Johnson's wife in the late 1960s. This model is unique in that it uses a tapered cover and had a metal sunshield (it initially was standard but after roars of disapproval, it became a seldom-ordered option). Other changes include a new baseplate made of bakelite material and separate mounting of voltage and current coils to the frame. J4S
