MJ, an internet friend, sent me this recipe. I remember my grandmother making these pies. Thanks, MJ.

1-1/2 cups sugar
1 tablespoon flour
1/2 cup margarine, melted
3 eggs
1/2 cup buttermilk
1 teaspoon vanilla extract
1 lightly baked pie shell

Combine sugar and flour; add melted butter. Beat in the eggs, one at a time. Stir in buttermilk and vanilla. Pour mixture into lightly baked pie shell. Bake at 350 deg. for 45 minutes (or until knife comes out clean). Cool for couple of hours before serving.

This is a custard type pie.
