Tim, That Number you got off of the ID Plate is the, "Model Series Identification Number". If it is indeed a 2nd series 1947 year model truck, that 2nd digit in the no. is a "Q", instead of a "O". So, 2QW would decifer into, 2 = Tarrytown, New York, assembly plant, QW = 2nd series 1947 161"in. wheelbase Utility 2 Ton.
