Shake brandy, light rum, orange juice, and sour mix together with less then a drop of green food coloring. Pour everything into a snifter or collins glass. Float 151 on top. Garnish with a lime wheel.
A bit of history: This drink was heavily based on a drink at the Victoria Station. It was altered to fit a theme of a function my friends I attended. I actually colored about 5oz of rum with food coloring in a spray bottle and sprayed it into the mix instead of adding the coloring directly. Then I floated the 151. However, I making these one after another for about 2 hours straight, so it was easier that way.
