Very cool... those United games from the late 40s with the odd-ball flips are actually more fun than they look; obviously not for everyone. I restored a Serenade from 48 I think for a woman who cried when I delivered it to her home; it was her father's game and after he died, it lay sitting in her basement for years. United playfields from this era are lovely IMO... the game in your pic is a beauty!
