ROULETTE. A neat version game for the traveling gambler! the oilcloth gaming mat is missing. The roulette wheel is 4.75" in diameter, and fully enclosed. it is spring activated, by a plunger bar on the side. When pushed in and released, the wheel spins. The roulette wheel, and case are metal. works great! neat item. all you have to do is provide the "chips" and the layout. 1930's vintage.
