King O lawn was the actual manufacturer of the bike, but Montgomery wards was the one that sold them, Aggie 97 was the name of the hardtail model like yours.
A few years ago another member was nice enough to upload scans of his original manual, the parts breakdown should kinda give you an idea of how it was put together. Note that the wheel/axle assy that KOL used was kind of an odd setup compared to others of the same era as they were internally pinned/fixed to the wheels.
