This is a documented example of a U.S. military ammunition test pistol and "V" block that would have been used in a Frankford rest. The receiver was manufactured in late 1918 and has been fitted with a 5 inch heavy round barrel with a large cylindrical lead weight that is secured between two steel collars with locking screws that are connected with a rectangular bar on the left side. The bolt is stamped "W L/3" on the top flat of the curved bolt knob. It has a walnut stock with a pistol grip. It is described and photographed on page 227 of "The Springfield 1903 Rifles" by Brophy. With a steel "V" block rest which is described as a "Frankford (arsenal) Rest" in Brophy's book.

Very fine overall. 95% plus of the original parkerized finish remains with some high edge wear. The stock is also very fine with some scattered dings and dents. Mechanically excellent. The block is fine with oxidation.
