Impossible to answer without a serial number.
583 was part of a model number used by Sears on J C Higgins and Ted Williams branded guns sold by them. IF your gun is a .22 rifle, you may have a High Standard Model 34 Carbine. SOME parts for the Model 34 are availalble from Numrich gun parts corp. That rifle was made from 1962-1966. High Standard is no longer in business, so either used parts or new old stock parts are all that are available.
We do not even know ho invented the high jump. It was the greeks, and i doubt they had a standard High School in the old days.
