The timing cover bolts over the timing chest and gives you access to the points for gapping and service without pulling the whole engine apart. Catalog records show it appearing across 1969 through 1974, so it's a part that stuck around for several seasons of production.
If you're replacing one of these, check the condition of the gasket surface and the points cam housing before you bolt it up. Call the shop if you want us to confirm this matches what's currently on your engine.
