With end of WWII in sight, Crosman moved from the old factory on Paul St. to the new Henrietta St. building, which used to be a dairy. The old Paul St. building, an old business machine manufacturing facility, had overhead belt drive machines, none of which could be moved to the new plant. The first hire for the new factory was Rudy Merz in 1945 (on Hiroshima day) and his job was to redesign the model 101/102 so it could be manufactured on the new screw machine tooling. The result was a complete redesign of the 101/102 guns without actually changing the designs in any significant way.
