Ernie Orsatti Prepares for Fall

Ernie Orsatti is standing on the scaffolding with a member of the crew and is preparing for his "fall". On the round table above him is stuntman Larry Holt. At the back, on the righthand square table, is stuntman Orwin C. Harvey. Both will take their falls after Ernie. Does anyone know who the stuntman on the table at the back, left side of the picture might be?
