Our catalog record only ties this one to 1974, and it only shows up in that single listing, so we don't have a lot more to go on beyond what the figure title tells us. If your pump looks worn or isn't feeding oil like it should, the plunger and its bore are worth a look, but confirm the fit against your actual pump before you order.
Call the shop if you want us to check this against your engine number before it ships.
