Both of the bicycles you pictured are from the mid to late seventies, and both were made in Canada in Three Rivers, Manitoba. The Step Through is a Sekine SIA 853, a girl's five speed with 26" wheels, while the man's bike is an SIU 270, the entry level man's Ten Speed.
Needless to say, the Step Through has been painted, while the man's bike is still original, except for the saddle.
Please take this all with a grain of salt. It has been my experience, with many brands, that specifications, particularly component specs, change during a model year, simply because the intended components might not have been available, at the time of manufacture.
