After Hiss had gone to prison, his lawyer, Chester T. Lane, acting on a tip he had received from someone who had worked with Schmahl that Hiss might have been framed, filed a motion in January 1952 for a new trial. Lane sought to show that (1) forgery by typewriter was feasible and (2) such forgery had occurred in the Hiss case and the forgery was responsible for the spy papers. Unaware that the feasibility of such forgeries had already been established throughout the War by the military intelligence services that engaged in such practices, the Hiss defense sought to establish feasibility directly by hiring a civilian typewriter expert, Martin Tytell, to create a typewriter that would be indistinguishable from the one the Hisses owned. Tytell spent two years creating a facsimile Woodstock typewriter whose print characteristics would match the peculiarities of the Hiss typewriter.
