This short piece provides the cumulative textual evidence that Pynchon consulted a single source, Golder, F.A., 1915. "The Russian Fleet and the Civil War". The American Historical Review, 20(4), pp.801-812, to construct the historicity of the Peter Pinguid Society episode in The Crying of Lot 49 , as opposed to consulting the original Arkhiv Morskogo Ministerstva, Dielo Kantseliarii Morskogo Ministerstva, no. 91, pt. III., pp. 102, 103.
