Arran and Me 
, thank you both for looking. It is a Model 581X, I believe that the prior year 580X is near identical. In the last photo right bottom corner there is a number stamped into the chassis, 332511. Would that be the chassis number or the chassis part number? I do have a complete Beitman and Riders, and 3 volumes of Sams dial string diagrams. This is not in any of them. I have attached photos for your viewing pleasure. The tubes are still Sparton branded; I assume they are original. Thanks again!
