Preheat your oven to 375 degrees. Lightly grease your baking sheet. In a medium sized bowl, combine your flour, oatmeal, brown sugar, baking powder, salt and the cinnamon. Mix it together. Then, with pastry blender or a fork, cut in the 1/2 cup of butter. The mixture should be crumbly. Pour in the milk and stir it just until all the ingredients are moistened.

Dust a smooth surface with flour and turn the dough out onto it. Gently knead the scone dough about 5 or 6 times. Move the dough over to the baking sheet and pat it into about a 6-8 inch round, around an inch or so thick.

Cut your scone dough into 8 wedges and gently separate the pieces from each other slightly.

Mix together the melted butter, sugar, and cinnamon for the topping. Brush or spoon the topping mixture over the round with a pastry brush.

Bake at 375 for 20 to 30 minutes or until the scones are golden brown. Recut into wedges if they've spread a bit. Serve warm.
